melting point of copper sulfate and is it ionic or molecularthanks for anyones help
Are you sure you mean Cu(III)? There are a few copper (III) compounds, but I can't find any reference to copper (III) sulfate. Perhaps you mean copper (II) sulfate. Copper (II) sulfate is not clearly ionic. The bonds between copper and oxygen are nearly 50 percent ionic (50 percent covalent). Copper (II) sulfate does not have a melting point, per se.
Cu3+ & SO4 is 2- charge. Both are ions.
