Ba2+(aq) + SO42-(aq) --> BaSO4(s)
The other ions, Cu2+ and Cl-, don't react (tribune ions).
Copper (II) sulphate, CuSO4 is prepared by mixing copper (II) oxide, CuO with sulfuric acid, H2SO4. CuO + H2SO4 --> CuSO4 + H2O
The precipitate is copper(II) hydroxide. The chemical reaction is:2 NaOH + CuSO4 = Cu(OH)2 + Na2SO4
Copper sulfate (CuSO4) is not hygroscopic. It is a stable compound that does not readily absorb moisture from the surrounding environment.
Assuming you mean a reaction between potassium (K) and copper(II) sulfate, your products would be potassium sulfate and copper in a single replacement reaction. Here's the equation:2K + CuSO4 --> K2SO4 + Cu
CuSO4 is the chemical formula of copper(II) sulfate.
CuSO4 + BaCl2 --> CuCl2 + BaSO4
BaCl2 + CuSO4 = BaSO4 = CuCl2
CuSO4(aq) + BaCl2(aq) -> CuCl2(aq) + BaSO4(s)
CuSO4(aq) + BaCl2(aq) = CuCl2(aq) + BaSO4(s) This is the classic test for sulphates. A white precipitate of barium sulphate forms.
The Cu2+ from CuSO4 is displaced by the Na+ from NaCl and CuCl2 and Na2SO4 are formed.
CuSO4 + 2HCl -> CuCl2 + H2SO4 copper chloride and sulfuric acid
These substances doesn't react.
CuF2+ K2SO4
The precipitate is copper(II) hydroxide. The chemical reaction is:2 NaOH + CuSO4 = Cu(OH)2 + Na2SO4
Copper (II) sulphate, CuSO4 is prepared by mixing copper (II) oxide, CuO with sulfuric acid, H2SO4. CuO + H2SO4 --> CuSO4 + H2O
Cu(OH)2 + (NH4)2SO4
Copper sulphate CuSO4
