Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu2 SO4. It is a white solid, in contrast to copper(II) sulfate, which is blue in hydrous form. Compared to the commonly available reagent, copper(II) sulfate, copper(I) sulfate is unstable and not readily available. [1]
Cu2SO4 crystallizes in the orthorhombic space group Fddd. Each oxygen in a sulfate anion is bridged to another sulfate by a copper atom, and the Cu−O distances are 196 pm. [1]
Cuprous sulfate is produced by the reaction of copper metal with sulfuric acid at 200 °C: [3]
Cu2SO4 can also be synthesized by the action[ clarification needed] of dimethyl sulfate on cuprous oxide: [4]
The material is stable in dry air at room temperature but decomposes rapidly in presence of moisture or upon heating. It decomposes into copper(II) sulfate pentahydrate upon contact with water. [4]
It can also be produced by the reaction of copper(II) sulfate and a reducing agent such as sodium thiosulfate.[ citation needed]
