Answer:
Hardness (mg/L). Degree of hardness. 0-75. Soft. 75-100. Moderately hard ... Total hardness is defined as the sum of the calcium and magnesium ... carbonate and bicarbonate alkalinity, amount of hardness equivalent to the total ... So, Hardness due to calcium ions = [15 mg/L × 50]/ (20) = 37.5 mg/L CaCO3 ... 20 mg/L Cl.
