The crystals of copper sulfate pentahydrate prepared from laboratories have different shapes and crystallographic planes. Based on the theory of crystal growth and the symmetry theory, this manuscript makes a rough explanation. According to crystallographic data, the microstructures of the currently known copper sulfate pentahydrate, trihydrate, and monohydrate are discussed. A new dehydration process and the microstructure of copper sulfate dihydrate are also proposed.

Key words: Copper sulfate pentahydrate, Copper sulfate trihydrate, Copper sulfate monohydrate, Crystallographic planes, Crystal structure
