Solution:
The given statement is true.Concept- Soaps and detergents are salts of fatty acids. While detergents are salts of ammonium and sulphate of long chain carboxylic acids, soaps are salts of sodium or potassium of long chain carboxylic acids.
While detergents exhibit significant cleaning effects, soaps have relatively little cleaning power. Hard water prevents soaps from lathering because it combines with soap molecules to produce an insoluble precipitate known as scum.
Soaps are salt of sodium and potassium to which an aliphatic chain is attached. It is prepared via saponification. Detergents are sodium and potassium salts at the end of which the sulfonate group is attached. They are soluble in hard water. So it is a true statement.
Hence, the correct answer is option 1.
