Scum forms are what we call soapless detergents, when a soap is used in hard water.The charged calcium and magnesium particles in the water react with soap to form an insoluble substance.
What is soap?When soap is being used in hard water, soap scum forms into a solid substance.The soap scum substance is made from calcium and magnesium particles that are in the water with the soap.
The detergents do not make scum with hard water because they react with magnesium and salt in the water.Scum is formed when detergents do not combine with Ca2+ ion present in hard water.
Why does soap scum form in hard water when it contains Ca2+ and fe3+ ion?
When soap is added to hard water, Ca2+ and Mg2+ ion react with each other.The calcium and magnesium salts that are present in soaps are precipitated as scum.The form of detergents is more lather than soaps.
