Calculating Calcium Hardness as CaCO3
The hardness (in mg/L as CaCO3) for any given metallic ion is calculated using Equation
Calcium hardness (m/L) as CaCO3/equivalent weight of CaCO3
= Calcium (mg/L)/equivalent weight of calcium
A water sample has calcium content of 51 mg/L. What is this calcium hardness expressed as CaCO3?
Referring to Equation:
x mg/L /50.045=51 mg/L [....]Read more
