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
5-Amino Phthalide Reacet with NaNO2+HCL to conversion of dizonium salt React with CuSO4+KCN To conversion of 5-cyano phthalide

5-Amino Phthalide Reacet with NaNO2+HCL to conversion of dizonium salt React with CuSO4+KCN To conversion of 5-cyano phthalide
Sodium hydroxide is the limiting reagent.
Al + CuSO4 --> Al2(SO4)3 + Cu
Cu + 2 H2SO4 --------------> CuSO4 + SO2 + 2H2O
The answer will depend on the quantity of KCN.
Since potassium cyanide (KCN) is highly poisonous, the addition of KCN to water might be caused by an intention to kill.
Most reactive metals, Zinc, being most common in practice, sodium Potassium Calcium etc
KCN kills a human being in 0.5 second.
