Tetraamminecopper(II)_sulfate
Tetraamminecopper(II) sulfate
Chemical compound
Tetraamminecopper(II) sulfate monohydrate, or more precisely tetraammineaquacopper(II) sulfate, is the salt with the formula [Cu(NH3)4]SO4·H2O, or more precisely [Cu(NH3)4(H2O)]SO4. This dark blue to purple solid is a sulfuric acid salt of the metal complex [Cu(NH3)4(H2O)]2+ (tetraammineaquacopper(II) cation). It is closely related to Schweizer's reagent, which is used for the production of cellulose fibers in the production of rayon.
