Question

what is the alternative for soaps while washing in hard water ? ​

Answer 1

Answer:

Synthetic detergents are used in the case of hard water also because the calcium and magnesium salts of detergents are soluble in water. Detergents are more soluble than soaps and hence form more lather than soaps.

Detergents are better cleansing agents than soaps because they can be used even with hard water. The charged ends of detergents do not form insoluble precipitates with calcium and magnesium ions in hard water. ... Detergents have a stronger cleansing action than soaps and are more soluble in water than soaps.
