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
Solubility of Al2(SO4)3 Al2(SO4)3 ⇌ 2Al3+ + 3SO2−4 Ksp = [Al3+]2[SO2−4]3
What is the correct equilibrium expression (Ksp) for the reaction below: Ca3(PO4)2(s) ⇌ 3Ca2+(aq) + 2PO42-(aq)
