Hi , I`ve a question . If a copper rod at positive terminal and iron rode at negative terminal are put in a zinc sulphate solution then what will be coated on the iron rode ? Copper or Zinc?

Dear student,

Zn is more reactive than Fe and Cu. Fe is more reactive than Cu.
So Zn will deposited on copper and displaced it more easily.

A beaker contains an acidified copper sulphate solution. A copper plate and a carbon rod are kept in this copper sulphate solution. The copper plate is connected to the positive terminal of a battery whereas the carbon rod is connected to the negative terminal of the battery. What will you observe when an electric current is passed through this set-up for a considerable time?

During electroplating the copper plate on the negative terminal gains weight and positive terminal having the copper plate loses weight. If this journey happens continuously what will happen to the positive copper plate as it will loose all the copper ions it contains? Will it dissolve into copper sulphate solution?
