Question

yaahoo if ca2+ = 30mg/l and caco3, total alkinity ta=20mg/l as caco3, ph=6.6, temperature=25c and ionic strength =0, how much lime must be added to make water asaturated solution of caco3

Answer 1

Answer:

Multiply alkalinity in "Eq/L" by the equivalent weight of CaCO3 to calculate it in g/L. In our example, Alkalinity as CaCO3 = 0.0097 Eq/L x 50 g/Eq = 0.485 g/L = 485 mg/L. Thus, if the solution density is close or equal to 1, then ppm = mg/L.
