Question

2. What happens when a piece of
a) Zinc metal is added to copper sulphate solution?​

Answer 1

Answer:

When zinc is added to copper sulphate (CUSO 4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless. The chemical equation of the reaction, Zn + CuSO 4 → ZnSO 4 + Cu

Explanation:

Answer 2

Answer:

zn(s) + CuSo4(aq) ----------> znSo4(aq) + cu(s)

Explanation:

As zinc is more reactive than copper so it displaces copper from its salt solution and form znso4 and the colour of solution turns blue to colorless during the process.
