Question
Give any two differences between soaps and detergents.
Solution
| Sl.No | Soaps | Detergents |
| 1. | Soaps are salts of sodium or potassium of the long chain carboxylic acids. The ionic group present in a soap is COO-Na+. | Detergents are salts of sodium of long chain benzene, sulphonic acids or long chain alkyl hydrogensulphates. The ionic group present in a detergent is SO3-Na+. |
| 2. | Soaps have weak cleansing action compared to detergents. | The cleansing action of detergents is stronger to that of soaps. |

A student takes four test tubes marked P, Q, R and S of 25 mL capacity and fills 10 mL of distilled water in each. He dissolves one spoon full of four different salts in each as − KCl in P, NaCl in Q, CaCl2 in R and MgCl2 in S. He then adds about 2 mL of a sample of soap solution to each of the above test tubes. On shaking the contents of each of the test tubes, he is likely to observe a good amount of lather (foam) in the test tubes marked
