Aim: To compare the foaming capacities of five different commercial soaps. Apparatus: 5 test tubes‚ 5 conical flasks (100 ml)‚ test tube stand‚ Bunsen burner and stop watch. Materials Required: 5 different samples of soap and distilled water Theory: The foaming capacity of a soap sample depends upon the nature of soap and its concentration. This can be compared for various samples of soaps by taking the same concentration of solution and shaking them.The foam is formed and the time taken
