Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]

Green vitriol is iron(II) sulfate heptahydrate, FeSO 4 ·7H 2 O; blue vitriol is copper(II) sulfate pentahydrate, CuSO 4 ·5H 2 O and white vitriol is zinc sulfate heptahydrate, ZnSO 4 ·7H 2 O. Alum , a double sulfate of potassium and aluminium with the formula K 2 Al 2 (SO 4 ) 4 ·24H 2 O , figured in the development of the chemical industry.
2 Cu + 2 H 2 SO 4 → Cu 2 SO 4 + SO 2 + 2 H 2 O. Cu 2 SO 4 can also be synthesized by the action of dimethyl sulfate on cuprous oxide: [4] Cu 2 O + (CH 3 O) 2 SO 2 → Cu 2 SO 4 + (CH 3) 2 O. 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 ...
The derived quantity relative molecular mass is the unitless ratio of the mass of a molecule to the atomic mass constant (which is equal to one dalton). [2] The molecular mass and relative molecular mass are distinct from but related to the molar mass.
One of the biggest decisions anyone has to make for retirement is where to invest money. If you ask 10 different financial advisors, there is a 100% chance you’ll get 10 different answers. This ...
Cu + 4 HNO 3 → Cu(NO 3) 2 + 2 H 2 O + 2 NO 2. The same salts can be prepared treating copper metal with an aqueous solution of silver nitrate. That reaction illustrates the ability of copper metal to reduce silver ions. In aqueous solution, the hydrates exist as the aqua complex [Cu(H 2 O) 6] 2+.
