Calculate the solubility of ZnCO3 in water at 25 °C.

Question

Calculate the solubility of ZnCO₃ in water at 25 °C. K_sp data is given below.

ZnCO₃ K_sp = 1.46 x 10^-10

Round your answer to 2 significant digits.

___g/L

Answer 1

ZnCO₃(s) <==> Zn²⁺(aq) + CO₃^2-(aq)

Ksp = [Zn²⁺][CO₃^2-]

1.46x10^-10 = (x)(x) = x²

x = √1.46x10^-10

x = 1.21x10^-5 M = 1.2x10^-5 M solubility of ZnCO₃ (2 sig. figs.)
