Forms of Copper Sulphate



May I know if copper sulphate comes in what forms? Why do they have different forms?


ps. This is NOT a homework assignment,okie?

Telling us that it is not a homework assignment, doesn't exactly supply the full context to enable us to answer your question properly, Cindy. The most common form of copper sulfate [linked by editor to product info at Amazon] is the blue crystal CuSO4.5H2O. But you can dissolve that in water and have it as a blue liquid, or you can heat it to drive out some of the water of hydration, and you would have anhydrous copper sulphate -- a white powder.
