Question: does znso4 dissolve in water?
Answer: ZnSO4 is soluble in water. Some sulfates are soluble and some are not. Generally, when cation is small, its sulfate is soluble, e.g. CaSO4, MgSO4, CuSO4, etc., but when cation is large, its sulfate becomes difficult to dissolve in water, e.g., BaSO4, PbSO4, etc.
