Answer 2

The key to a great presentation is demonstration.

Take your stock Store soap solution as Sample 1, dilute It ten times and label this Sample [Solution] 2; dilute Sample 2 ten times and label this Sample 3. Shake or stir each of these for equal Time intervals and measure the amount of Time it takes for the bubbles to disperse.

Answer 3

The foaming capacity of a soap or detergent refers to the amount of foam that can be produced by agitating soap in a container filled with an equal amount of distilled water. After being shaken well, the solution is allowed to sit still and settle. The longer it takes for the foam to dissolve, the greater is its foaming capacity.

Answer 4

introduction of foaming capacity of soap :- soaps samples of various brands are taken and their foaming capacity is noticed. Various soap samples are taken separately and their foaming capacity is observed. The soap with the maximum foaming capacity is thus, said to be having the best cleaning capacity. The test requires to be done with distilled water as well as with tap water. The test of soap on distilled water gives the actual strength of soaps cleaning capacity. The second test with tap water tests the effect of Ca++ and Mg++ salts on their foaming capacities.

Effect of adding of sodium carbonate on soap :- adding sodium carbonate to soap can affect the activity of the soap in different manners in presence of different types of water. For example on case of hard water it will precipitate calcium carbonate and hence, activity of soap will improve. But in presence of fresh water it will reduce the inter-facial tension but bubbles of soap will not be formed. In presence of saline water addition of sodium carbonate may increase pH resulting in scale formation of calcium carbonate. However, in general the foaming capacity of detergents is not affected to a very large extent by addition of sodium carbonate.
