Question

A water presents a total hardness of 35 ° F and an HCO3- ion content of 427 mg/L. Calculate
the carbonate and non-carbonate hardness expressed as mg/L Caco..​

Answer 1

Explanation:

Total Hardness is 136 mg/l i.e. 2.72 epm

M alkalinity is 267 mg/l i.e. 5.34 epm

Carbonate is 2.72 epm or 81.6 mg/l

Non carbonate is 5.34-2.72= 2.62 i.e. 159.82 mg/l
