When hard water is treated with soap. soap does not work properly when the water is hard. ... when soap is added to hard water, calcium and magnesium ions present in water displace sodium or potassium ions from the soap molecules forming an insoluble substance called scum.

Hello
Soaps are sodium or potassium salts of higher fatty acids. Harness in water due to the presence of Ca^2+ions and Mg^2+ion, present as their salts.The soap first reacts with calcium and magnesium ions to form insoluble precipitate of calcium and magnesium salts of fatty acids which float as an off white layer over water.This layer is called scum.
Hope it helps
