Question

Take two test tubes with about 10ml of hard water in each. Add 5drops of soap solution to one and five drops of detergent solution to the other. Shake both test tubes for the same period. Do both test tubes have the same amount of foam?

Answer 1

both test tubes have different amount if foam
in soap solution test tube Curdy solid is formed as detergent works in both hard water and soft water but soap works in only soft water. so there would be less foam

Answer 2

When soap and detergent are added to two different test tubes containing hard water the foam is much more in the test tube having detergent than in a test tube having soap.

• Hard water contains ions of calcium and magnesium bicarbonate which are difficult to remove and do not bind easily with the ions of soap while soft water contains calcium and magnesium sulfates and chloride which can be easily removed.
• The hard water is passed through many processes such as boiling and passing through cation exchange resins to convert into soft water.
• Foam is easy to form with soft water than hard water while detergents can form foam both in hard and soft water while soap does not form foam easily.
