Question

The solubility product constant for SrCO 3 is 3.5 * 10 ^ - 8 at 25°C. The solubility of SrCO 3 is ______ M

science chemistry

Answer 1

Answer #1

SrCO₃(s) = Sr⁺²(aq) + CO₃^-2(aq)

Ksp = [Sr⁺²][CO₃^2-]

Note = solid and liquid state does not count in equilibrium calculations

3.5*10^-8 = X²

squareroot(3.5*10^-8) = X

hence X = 1.9*10^-4M

hence solubility of SrCO3 is 1.9*10^-4M
