Help on Solubility Product Constant?

Question

Could someone please explain would a larger Ksp value have a more or less soluble the salt and why? I would greatly appreciate anyone's help!

Answer 1

For a salt, say, AmBn,
Ksp=[A]^m[B]^n,
so a larger value of Ksp would mean the salt is more soluble, that is, the concn's of A and B in the solution (at equilibrium) are high.

Answer 2

for example CaSO4 <---> Ca 2+ + SO4 2-
ksp =[Ca2+] * [SO4 2-] / [CaSO4] [] means mole when they reach the equilibrium state
so the more ksp is, the more soluble the salt is
