The molar solubility of aluminum phosphate in a
water solution is M?
The molar solubility of iron(II) carbonate in a
water solution is M?
AlPO4(s) ----------------> Al^3+ (aq) + PO4^3- (aq)
x x
Ksp = [Al^3+][PO4^3-]
1.3*10^-20 = x*x
x^2 = 1.3*10^-20
x = 1.14*10^-10
solubility of aluminum phosphate = 1.14*10^-10 M
FeCO3(s) ----------------> Fe^2+ (aq) + CO3^2- (aq)
x x
Ksp = [Fe^2+][CO3^2-]
3.13*10^-11 = x*x
x^2 = 3.13*10^-11
x = 5.6*10^-6
The solubility of iron(II) carbonate = 5.6*10^-6 M
