Question

One strategy for dealing with the acidification of lakes is periodically to add powered limestone (CaCO3) to them, resulting in pH of 10.95. Calculate the Ca2+ concentration in the lake.

CO2 in atmosphere 370 ppm

KH,CO2 = 0.033 mol/(L∙atm)

Ka1 = 10-6.3

Ka2 = 10-10.3

Ksp,CaCO3 = 4.57 x 10-9
