The solubility of a salt of weak acid (AB) at pH 3 is Y×10–3 mol L–1. The value of Y is
(Given that the value of solubility product of AB Ksp=2×10–10 and the value of ionization constant of HB Ka=1×10–8)
The expression for the solubility product of Al2(SO4)3 is
Ksp = [Al3+] [SO42-]
Ksp = [Al3+]2 [SO42-]3
Ksp = [Al3+]3 [SO42-]2
Ksp = [Al3+]2 [SO42-]2
