Soaps are not effective cleansing agents in hard water because of the formation of a curdy precipitate or scum. This scum is created when soaps react with the calcium and magnesium ions present in hard water.

Explanation:
When we apply soap, it reacts with the calcium and magnesium ions of hard water to form insoluble precipitate called scum. Scum sticks to the clothes, restricting the cleansing ability of the soap.
