Question

Q.A manganese plate was put into a solution of copper sulphate kept in a glass container.It was found that the blue colour of the solution gets fader and fader with the passage of time.After few days,when manganese plate was taken out of the solution,a number of holes were observed in it.
(i)State the reason for changes observed on the manganese plate.
(ii)Write the chemical equation for the reaction involved. ​

Answer 1

Answer:

1) The reason for the holes is that the zinc reacts with copper sulphate to form zinc sulphate, a colorless solution, and the displaced copper settles down as precipitate. So, the zinc plate gets holes in it from where the zinc ions leave to combine with the sulphate ions.

Explanation:

1) The reason for the holes is that the zinc reacts with copper sulphate to form zinc sulphate, a colorless solution, and the displaced copper settles down as precipitate. So, the zinc plate gets holes in it from where the zinc ions leave to combine with the sulphate ions.

Answer 2

Answer:

this is because manganese displace the copper from its salt solution .

and the copper form reddish brown layer on manganese plate.

1. the copper metals has slowly deposited on manganese plate And hence manganese metal goes out forming holes in the plate.
