The goal of this laboratory project was to test which ingredient (fat oil) makes for the best soap using the properties of fats/ oils. Another goal was to test the soap, detergents, and their waste water to decide which is the most effect eve and environmentally friendly. The group was also to determine what was causing t he scum after washing and figure out a solution to stop it. We will write a custom essay sample on Soap Lab or any similar topic only for you Order Now Experimental Design To achieve the above goals, four different types of soaps and two detergents were made with certain ingredients and the desirable properties were taken onto account. The waste water of each soap and detergent was titrated to determine en how the waste water would affect the environment. To make four different types o pop, we used ;o oils, vegetable oil and olive oil, and two fats, shortening an d lard. 10 ml of the oils and log of the fat were obtained in a mill beaker. 15 ml of 6 M sodium hydroxide and about 1 ml of glycerol were added to each ingredient drop by drop then mixed thoroughly with a glass rod. The solution was then heated with a heating plate to boiling until it became pasty. After the pas tee cooled, 50 ml of saturated sodium chloride solution and ice was mixed into t he solution. The soap was then filtered using suction filtration and washed with t ml portions of cold water. Each filtrate was saved separately. Two methods ere used for making detergents. The first method required 4 ml of laurel alcohol t o be placed in a mill beaker. While stirring, 2 ml of concentrated sulfuric acid w added to the beaker. While to mixture sat for 10 minutes another mill BEA Kerr was filled with ice, log of sodium chloride, and water until the total volume w as 75 ml. Then, in a ml beaker, 5 ml of 6 M sodium hydroxide and 10 ml of watt were mixed. Four to five drops of phenolphthalein to the sodium hydroxide solution. After the 10 minutes, the sodium hydroxide solution was added to t he sulfuric caudally alcohol mixture until the pink color produced by the honorableness faded. The solution was poured into the saltwater bath an stirred until the clumps were broken up. The second detergent was made AC Roding to method II. 5 ml of laurel alcohol was carefully added to 5 ml of concentrate sulfuric acid. In another beaker, 3 drops Of phenolphthalein was added to 10 ml of 6 M Noah. Then, the acidic solution of laurel alcohol was added to the Noah solution with constant stirring until the pink color faded. Both detergents were e filtered using vacuum filtration and saved for the following weeks tests. The following week, solubility, cleaning, and lathering tests were performed o determine which soap and detergent cleaned the best. The wastewater WA s also analyzed from the processes of making the soaps and detergents. In addition, the contaminants and the environmental impact of the wastewater were identified deed. After these tests were conducted, the group had to decide which soap or detergent would be best for the environmental group to use. To test the solubility of each soap and detergent, appeased clumps of each were added to ml of water, acetone, an ethyl acetate. To test the cleaning abilities of each soap and detergent, a wet paper towel was used with samples of each soap and detergent to clean a dirty spot he lab counter. Cleaning abilities were measured by the amount of residue a ND dirt left behind. Lathering of the soap and detergents were tested by adding Pease zed clumps of each to water and determining how many bubbles were produced. The more bubbles that were produced, the better the lathering was. To test the contaminants and environmental impact of the wastewater we used titration. Sing 5 ml filtrate of our vacuumed filtering and 45 ml of H2O the group first tested t pH of each filtrate. If a pH over 7 was found the group slowly added HCI and t drops were counted by a sensor and the initial and final volumes were also re order from the burette. If a pH under 7 was found, then Noah was added to the filter ate. The most environmentally friendly wastewater was determined based on the volume of iterant added. A lower volume of iterant was more desirable because it me ant that the wastewater could be more easily neutralized. The final week, the best soap’s and detergent’s solubility was tested in different types of water. Well water, pond water, and tap water are the waters that were used. Then, the pond water and well water were tested for contaminant s. If the water contained calcium ions, DEED was added to the water to get rid of them he water was acidic, the base Noah was added to neutralize the water. How to cite Soap Lab, Papers

Psychoanalytic Theory and Subjectivity †Free Samples to Students

Question: Discuss about the Psychoanalytic Theory and Subjectivity. Answer: Introduction Readers are informed of how Esther created an enthralling and compelling picture of a teenager undergoing her worst nightmare. This is because she was fighting against the identity of being called Esther. Based on some parts of novel such as I am not Esther. Im Kirby and in the second quote Im Kirby, I yelled. Im not Esther, for Gods Sake. When her mother informs Esther that she is going away and that she is going to leave her with relatives that she has not heard off, she becomes disappointed especially when she learnt that they belonged to strict religious cult (Beale, 2004). Her devastation arises from the fact that she is forced to change her name from Kirby to Esther and she is also forced to adhere to a severe set of social standards which have been put in place by the strange cult. It is quite apparent that there are rules which Esther is supposed to follow and among them is rule number 10 which quoted here A Daughter respects her elders. She is modest. She does not draw attention to herself Through this quotation, it is apparent that Aunt Naomi was telling Kirby (Esther) new rules to ensure that she lived by The Rule. This is clearly freedom of both identity and expression. About Uncle Calebs assertion that The women of our faith always dress with modesty (Sly, 2004). This is a clear indicator that Esther is forced to wear the garments that she is not comfortable with. Based on the above reading, it is quite apparent that the issue of identity has highly manifested itself. References Beale, F. (2004). I am not Esther. Disney-Hyperion. Sly, C. (2004).

(Month ly:  £6.0bn budget deficit, March 29, 2010; Tanweer, Thompson, n.d.). Keeping these issues in mind the government has taken a deficit reduction strategy. This set the path to Mr. Alistair Darling, Chancellor of the Exchequer to take an aggressive decision towards the reduction of debt.

Mr. Darling intends to reduce the general government spending excluding capital investment, interest on debt and social welfare costs by almost 1.5 per cent and 2 percent in 2011 and 2012 respectively.

Report for after presentation 2 - Essay Example Preston is of the opinion that even though the content might seem as if it was inadequate, this is contrary to the actual situation because the presentation utilized its space well to answer the questions effectively and logically. In addition, as a member of the audience, I appreciated the fact that the presentation was short since very long presentations dissuade the members of the audience from actively participating in it (Preston, 2007). According to Dare, the issue of ethics and integrity are clearly discussed, courtesy of the effective use of visual aids in this presentation. The use of bright colors (yellow) and high quality images that coincide with the message trying to be relayed, was very effective. In addition, the application of the high quality pictures and other graphics made the presentation, more appealing to the audience. However, despite the many strengths of the presentation, I felt that the use of incorrect tenses in some sections, such as in the summary, was a major flaw. Even though the presentation is not very formal, the use of correct tenses is essential in conveying the message effectively. If the group can correct this weakness then the presentation would be more effective (Dare, 2010). The presentation on how to purchase ethical chocolate is very informative. The presentation outlines comprehensively how chocolate sold in retail chains across the globe is a by- product of child slavery in Ghana. The agony experienced by the children is discussed in depth so that the audience can be educated on how to prevent this phenomena from occurring. One of the strengths of the presentation is its effective application of visual aids aimed at capturing the attention of the audience and also placing emphasis on the issue of child slavery. For instance, the picture of a child struggling to carry a sack of cocoa is very moving. The agony and hardship expressed on the child’s face is very effective. It is especially

Midshires College of Midwifery and Nursing Essay

Midshires College of Midwifery and Nursing - Essay Example The Steering Group had a total of 24 members derived from ten local Health Authorities, the NHS Hospital Trust and the Regional Health Authority. The members had various capacities such as General Managers, Chief Nursing Officers and some were representatives. The inclusion of General Managers from the ten Health Authorities was important since the five colleges provided services to hospitals in the ten Health Authorities. Their views, therefore, were needed to ensure that the creation of Midshires College of Midwifery and nursing becomes a success. The Steering Group had one main objective, which was amalgamating the five different colleges of midwifery and nursing. Although the Steering Group had a clear objective and the members needed to achieve its objective, it faced various problems in the process of creating Midshires College. The first problem encountered during the process of amalgamating the five colleges was the uncertain future regarding the demand for nurse education. T he number of nurses needed, and their functions in the health sector in the coming future were not clear. In this case, it was certain that nurses’ jobs faced a threat. If formed, Midshires College would face the problem of not admitting enough students to purse the midwifery and nursing course. The future of nursing jobs was measured in terms of population growth and establishment of new hospitals. It was only natural that when creating a new college, it had to accommodate more students than the other five colleges accommodated in total. However, there was a low demand for more nurses in the future market (Hughes et al, 2009). The second problem experienced when creating Midshires College was a conflict of interest between members in the Steering Group and the new college to be formed. In the five colleges, the General Managers were charged with the task of providing nursing education. It was apparent that, the new college, Midshires, if created could not rely on direct nurs e education services from the General Managers. The General Managers had the option of putting up a tender, which could see to it that they secure the contract of training nurses in the college. The objective and goal, which Midhires College was based on, contradicted both the intentions and interests of General Managers who formed the Steering Group. The creation of Midshires College faced a challenged, which came from the same people who were supposed to oversee its creation. A definite competition was on the rise, as it was seen when an organization to compete with the new college in terms of availing post-experience nurse education was formed by two Health Authorities. The Steering Group had the intention of frustrating efforts that the new college was making in order to provide post-experience courses. It is worth noting that the Steering Group was all along protecting its interests, through lamenting that if the new college provided post-experience courses then 30% of the five colleges’ staff would lose their jobs. Creating the new college became a challenge since members in the Steering Group were opposing change, which would affect jobs and provision of nursing education (Hughes et al, 2009). The third problem came as a result of the expectation that a higher educational institution would validate qualifications achieved from Midshires College, which was on the verge of formation. It was also expected that, in the end, Midshires College
