Solution
Ksp of CoCO3 = 1*10^-10
CoCO3 (s) -----------------> Co^2+ (aq) + CO3^2- (aq)
s s
Ksp = [Co^2+][CO3^2-]
Ksp = s*s
Ksp = s^2
1*10^-10 = s^2
s^2 = 1*10^-10
s = 1*10^-5 mole/L
molar mass of CoCO3 = 118.94g/mole
solubility of cobalt(II) carbonate = 1*10^-5 mole/L
= 1*10^-5 mole/L * 118.94g/mole
= 1.1894*10^-3g/L
= 1.1894mg/L
The solubility of CoCO3 = 1.1894mg/L](https://image.slidesharecdn.com/pleasewritecarefullyandexplainclearly-thankyou-solutionkspofc-230131022157-5a24643c/85/please-write-carefully-and-explain-clearly-Thank-you-SolutionKsp-of-C-docx-1-320.jpg)
