Question

If water contains dissolved calcium hydrogen carbonate, out of soaps and synthetic detergents which one will you use for cleaning clothes ?

Open in App
Solution

Calcium hydrogen carbonate reacts with soap to form insoluble compound. It reduces the cleaning capacity of the soap.

3RCOONaSoap+Ca(HCO3)2(RCOO)2(ppt)Ca+2NaHCO3

Synthetic detergents do not form such compounds so they can be used for cleaning clothes with water containing dissolved Ca(HCO3)2.
