Give the solubility product?

Give the solubility product constant expression for BaSO4.

BaSO3(s) ⇌ Ba^2(aq) +SO4^-2(aq)

(btw in SO4^ the 2 is a negative)

thank you

Ksp of BaSO4 :
Ksp = [Ba 2+] [[SO4 2-]
Because from the dissociation equation [Ba2+ ] = [SO4 2-] = [BaSO4]
you can say
Ksp BaSO4 = [BaSO4]²
