- 1. Multiple Choice
The Ksp expression for a saturated solution of Ca3(PO4)2 is
Ksp = [Ca2+][PO43-]
Ksp = [3Ca2+][2PO43-]
Ksp = [Ca2+]3[PO43-]2
Ksp = [3Ca2+]3[2PO43-]2
- 2. Multiple Choice
The molar solubility of silver sulphide is 5.0 x 10-17 mol/L. Calculate its solubility product.
Ksp = 5 x 1049
Ksp = 5 x 1033
Ksp = 5 x 10-49
Ksp = 5 x 10-33
