Correct Answer: Dtergents give lather even with  hard water


Solution : Correct Answer is Dtergents give lather even with hard water

In the case of detergents, more lather is formed in hard water than in soft water.
Water hardness is caused by the presence of calcium and magnesium salts. In hard water, detergents do not create insoluble precipitates with the calcium and magnesium ions.
