Sodium hydroxide is the limiting reagent.
CuSO4 + KCN --->Cu(CN)2 + K2SO4
CuSO4 is copper (II) sulfate. The balanced equation for CuSO4 with water is CuSO4 + H2O reacts to become Cu+2 + HSO4-2 + OH-.
Copper sulphate CuSO4
Copper sulfate dissolves in water, it does not react.
CuO + H2SO4 --> CuSO4 + H2O
CuSO4 + KCN --->Cu(CN)2 + K2SO4
CuSO4 is copper (II) sulfate. The balanced equation for CuSO4 with water is CuSO4 + H2O reacts to become Cu+2 + HSO4-2 + OH-.
Copper sulphate CuSO4
Copper sulfate dissolves in water, it does not react.
CuO + H2SO4 --> CuSO4 + H2O
Al + CuSO4 --> Al2(SO4)3 + Cu
Cu + 2 H2SO4 --------------> CuSO4 + SO2 + 2H2O
Most reactive metals, Zinc, being most common in practice, sodium Potassium Calcium etc
CuCO3 + H2SO4 --> CuSO4 + CO2 + H2OThe products are a salt, copper sulfate, carbon dioxide gas and water.
Yes. They do not contain the same proportion of CuSO4, however. The moles of CuSO4 . 5 H2O are more massive.
HCl + CuSO4
CuSO4 . 2H2O
