Determination of water hardness

Determination of water hardness

Introduction :

When water contain Ca²⁺, Mg²⁺, and HCO^3– ions in high amount or number than we called it hard water.

Find out the original Normality of a Secondary standard substrates solution

Find out the original Normality of a Secondary standard substrates   solution

Primary standard substrates are Na₂CO₃(Lab grade), Oxalic Acid(Lab grade) etc.

Secondary standard substrates are HCl , NaOH etc.
