Question

would u be able to check if water is hard by using detergent

Answer 1

No we cannot check because soap can only be used in this process

Answer 2

NO. DETERGENTS ARE SODIUN AND POTASSIUN SALTS OF SULPHURIC ACID OF HYDROCARBONS OF ALENE TYPE .

UNLIKE SOAP IT DOES NOT REACTS WITH CALCIUM AND MAGNESIUM IONS PRESENT IN THE HARD WATER TO FORM SCUM . IT FORM GOOD AMOUNT OF LATHER BOTH IN HARD WATER AS WELL AS SOFT WATER . THEREFORE DETERGENT WILL NOT ABLE TO CHECK IF THE WATER US HARD
