Salt Selection and Buffer Preparation - Sigma-Aldrich

At a given concentration, ammonium sulfate often gives the best resolution when compared to other salts and can be used at concentrations up to 2 M. Concentrations up to 3 M are usually required when using sodium chloride. Sodium sulfate is a very good salting-out agent, but problems with protein solubility may exclude its use at high ...

Barium chloride and potassium sulfate are both ionic compounds. We would expect them to undergo a double displacement reaction with each other. BaCl 2 + K 2 SO 4 BaSO 4 + 2 KCl By examining the solubility rules we see that, while most sulfates are soluble, barium sulfate is not. Because it is insoluble in water we know that it is the precipitate.
