Question

1g of CaCO3 is dissolved in 1lit of distilled water.50ml of this solution consumes 27ml of EDTA solution for titration. 50 ml of hard water sample requires 33ml of EDTA solution for titration. Same water on boiling and filtering requires 11ml of EDTA solution. Calculate all type of hardness of water.

Answer 1

Explanation:

Hardness can thus be defined as the soap-consuming capacity of a water sample, or the capacity of precipitation of soap as a characteristic property of water that prevents the lathering of soap.
