Foaming Capacity of Soaps investigatory projects chemistry class 12 cbse Theory: The foaming capacity of soap depends upon the nature of the soap and its concentration. The test of soap on distilled water gives the actual strength of the soaps cleaning capacity. The time taken for the foam to disappear in each sample is determined. An array of saponifiable oils and fats are used in the process such as olive, coconut, palm, cocoa butter to provide different qualities. It is used as laundry soap. Hot-process soap making was used when the purity of alkali was unreliable. This may be compared by shaking equal volumes of solutions of different samples having the same concentration with same force for the same amount of time. A cold-process soap maker first looks up the saponification value of the fats being used on a saponification chart, which is then used to calculate the appropriate amount of alkali. In a chemical sense soap is a salt made up of a corboxyli… There are varying levels of trace. Soaps and detergents remove dirt and grease from skin and clothes. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Soaps are useful for cleaning because soap molecules have both a hydrophilic end, which dissolves in water, as well as a hydrophobic end, which is able to dissolve non polar grease molecules. Soaps are sodium or potassium salts of higher fatty acids (containing 15-18 carbon atoms) e.g., stearic acid, oleic acid and palmitic acid. The hot, soft soap is then spooned into a mold. Parts of this project have been referred from foreign sources and have been included in this investigatory project after editing. Various soap samples are taken separately and their foaming capacity is observed. Sometimes castor oil can also be used as an ebullient. In the hot-process method, alkali and fat are boiled together at 80–100 °C until saponification occurs, which the soap maker can determine by taste or by eye. For example, olive oil provides mildness in soap; coconut oil provides lots of lather; while coconut and palm oils provide hardness. Once both substances have cooled to approximately 100-110°F (37-43°C), and are no more than 10°F (~5.5°C) apart, they may be combined. Soap can also be made of vegetable oils, such as palm oil, and the product is typically softer. Cleansing Action of Soaps and Detergents.
