The solubility of barium carbonate, BaCO3, is 0.0100 g/L. Its molar mass is 197.3 g/mol. What is the Ksp of barium carbonate?

Solutions

Expert Solution

Solubility (s) of BaSO4 = 0.0100 g/ L = 0.0100/197.3 mol/L = 5.0 X 10^-5 mol/L

BaSO4 <=======> Ba²⁺ + SO4^2-

Solubility (s): s mol/L s mol/L s mol/L

Solubility product for this reaction: Ksp = [ Ba²⁺] X [SO4^2-]

or, Ksp = [s][s]

Ksp = s²

Ksp = [5 X 10^-5]²

Ksp = 2.5 X 10^-9
