Description : Which method will be employed to test the hardness of water? (1) Boiling (2) Distillation (3) Formation of lather with soap (4) None of these
Last Answer : (3) Formation of lather with soap Explanation: Soap solution is used to measure the hardness of rain water, temporarily hard water and sea-water. Hard water does not form soap lather. This is ... in hard water react with soap to form calcium stearate or magnesium stearate and thus forms scum.
