Book Free DemoWrite a long answer to the following question:
What happens when a piece of
(a). zinc metal is added to copper sulphate solution?
(b). aluminium metal is added to dilute hydrochloric acid?
(c). silver metal is added to copper sulphate solution?
Also, write the balanced chemical equation if the reaction occurs
(a). zinc metal is added to copper sulphate solution?
(b). aluminium metal is added to dilute hydrochloric acid?
(c). silver metal is added to copper sulphate solution?
Also, write the balanced chemical equation if the reaction occurs
a. When zinc is added to copper sulfate solution due to the high reactivity of zinc, the copper is by the zinc to form zinc sulfate. During the reaction, the colour of the solution changes from blue to colourless.
The balanced chemical equation of the reaction is \(Zn\) + \(CuSO_4\) → \(ZnSO_4\) + \(Cu\)
b.
In this reaction, aluminium reacts with dilute hydrochloric acid to form aluminium chloride and gas.
In this reaction, aluminium reacts with dilute hydrochloric acid to form aluminium chloride and gas.
The balanced chemical equation of the reaction is
\(2Al\)(s) + \(6HCl\)(aq) → + \(3H_2\)(g)
c. When silver is added to the copper sulfate solution, occurs as silver is less reactive than copper; therefore, it can not copper from its solution.
\(Ag\) + \(CuSO_4\) →
