Saponification - Lab Report Example Although soaps and detergents are surfactants they are different in that sops are made from natural products while detergents are made from man-made product which may have some negative effect on the environment. Soaps work through a process called emulsification. This is where soap combines with non water soluble agents detaching them from the material. A micelle can be found in colloidal electrolyte solutions of soaps and detergents. It is formed from an aggregate of molecules resulting in charged particles (Herz 136). Formation of potassium soap is as a result of carboxylate anions and univalent cation to form a soap salt. A mixture of anions is due to the fatty acid residue present in the triglyceride molecule. No precipitate is formed with water because potassium soaps are highly soluble. The experiment was a success as potassium soap which was the required product was achieved at the end of the experiment. The potassium soap was able to remove grease thus proving the efficiency of the product. Hard water contains minerals that easily react with soap to form a solid precipitate called scum, detergents do not react with the minerals in hard water thus the lack of scum while using detergents, this one demerit of using soap over detergent. Soap is cheap and does not damage the fabric compared to detergent. Detergents on the other hand are effective against tough stains compared to soaps (Herz

If there are only a few people who buy the tickets or the drinks, the players’ salary decreases. Q.1. When there is underutilization, a country uses fewer resources than those that it can use. The production possibilities frontier is that line on the production possibilities graph which indicates the maximum possible output. Q. 2. The Product Possibilities Curve abbreviated as PPC shows the optimum production level hat economies can attain. For example, if a person compare the main level of production for an economy, with the actual curve, it is possible to determine the economy’s efficiency. Q. 3. Opportunity cost is demonstrated when making a comparison between data on different points on the production possibilities frontier. When the production of an element goes up, the curve on the PPC shows the production curve decreasing. Q. 4. If there is a decrease it does not mean that the production possibilities for farm’s output have decreased. If the decrease in farms was higher than the production possibility then the farm output would increase and vice versa. Q. 6. Certain events such as natural disasters for example, floods and hurricanes are likely to move the PPC down and to the left because there would be a reduction of productivity in the economy since most businesses in operation. Q. 6. Repairing a leaking roof and paying the night security guard are fixed costs because the payment does not change despite the events surrounding the expenses. Cotton, food and electricity at the mill are variable because they always change. Q. 3. Regulations affect the output decisions of producers because it may make it too expensive or cheaper. For example, companies will not continue to supply if the regulations support the expensive
