General description

It used largely as is or as a precursor in the production of numerous other compounds. The pentahydrate is soluble in alkaline solutions. Upon heating to 100oC in dry air, the pentahydrate converts to trihydrate.

Application

  • Chemical Synthesis: Synthesis and characterization of a new copper(II) chelate complex, exploring the crystal and molecular structure of aqua-(diethylenetriamine-N,N′,N′′)-copper(II) sulfate monohydrate (Lavrenyuk et al., 2015).
  • Material Science: Use of copper(II) sulfate pentahydrate in the dissolution of malachite ore and precipitation of copper sulfate pentahydrate crystals, highlighting a method for copper recovery (Kokes et al., 2014).
  • High-Pressure Studies: Application of high-pressure techniques to study the structural changes in copper sulfate pentahydrate, using a miniature diamond-anvil cell (Novelli et al., 2022).
