Ksp = ____
Answer
Give the solubility product constant for the following chemical equation:
BaSO4(s) ⇌ Ba2+(aq) + SO42-(aq)
Ksp = [Ba2+][SO42-]
We don't have a denominator, which would usually be the reactant concentration, but since it is a pure solid as our reactant then we exclude it from the equation.
