Question

Measurement of cloride, sulphate and salinity of wanter samples by simple titrationmethod(AgNo3 and potassium chromate)​

Answer 1

Answer:

To determine the amount of chloride (in the form of Cl–) present in the given water sample by Mohr's method. If water containing chlorides is titrated with silver nitrate solution, chlorides are precipitated as white silver chloride. Potassium chromate is used as indicator, which supplies chromate ions.
