Solubility Product

The least soluble salt (barite, K SP =10-10), contributes a negligible amount of sulfate to the solution. The more soluble salt (gypsum, K SP =10-4.6) supresses the solubility of the less soluble salt (the common-ion effect). Barite can replace gypsum because barite is less soluble than gypsum.
