Solid cobalt(II) carbonate is put into pure water and an equilibrium is established. The Ksp for CoCO₃ is known to be 1.0 x 10^-10. What is the concentration of CO₃^2- ions in the equilibrium mixture of CoCO₃?

Solutions

Expert Solution

CoCO3(s) ----------------> Co^2+ (aq) + CO3^2- (aq)

s s

Ksp = [Co^2+][CO3^2-]

1*10^-10 = s*s

s^2 = 1*10^-10

s = 1*10^-5 M

[CO3^-] =s = 1*10^-5 M

The solubility of CO3^2- is 1*10^-5 M >>>answer
