| General description: | Copper(II) sulfate (CuSO4) is an anhydrous copper(II) salt. It can be synthesized from CuSO4.5H2O, via dehydration. Copper(II) sulfate adsorbed on silica gel participates in the conversion of secondary and tertiary alcohols to olefins. Copper(II) sulfate-alumina has been employed as a solid-reagent system during the synthesis of benzils. |
