Question

zinc kept in copper sulphate solution​

Answer 1

Answer:

When zinc metal is added to a solution of copper sulphate (CuSO

4

), the blue colour of the latter changes to colourless as zinc sulphate (ZnSO

4

) is formed.

In this displacement reaction, zinc being more active metal than copper displaces it to form zinc sulphate, as shown below:

Zn(s)+CuSO

4

(aq)→ZnSO

4

(aq)+Cu(s)

(blue) (colourless)

Answer 2

Answer:

Copper is less reactive than zinc. Zinc will replace the copper from its salt solution. When the copper sulphate solution is stored in a zinc pot, copper is replaced by zinc, in the copper sulphate solution.
