Does sodium sulfate react with calcium hydroxide? What are the reaction conditions? When enough of these substances are used, a precipitate will form, but this depends on the circumstances 　　OH-NO3-Cl-SO4 2-CO3 2- Na+ soluble (sodium hydroxide) soluble soluble soluble soluble Ba 2+ soluble soluble soluble insoluble insoluble Ca 2+ slightly soluble (slaked lime) soluble soluble slightly insoluble

I don’t think so. Calcium sulfate has a higher solubility than calcium hydroxide.

This should indicate the formation of a precipitate. Na2SO4 + Ca(OH)2 = CaSO4↓ + 2NaOH

No reaction, because the base produced is more basic than the reactants; the presence of a precipitate indicates that it has become saturated
