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?

Solution

All the copper in copper plate will be electroplated on negative terminal.Eventually copper plate become empty.

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?

If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the positive terminal of the battery.

If plus sign (+) denotes the positive electrode and minus sign (-) denotes the negative electrode, then which of the following statement is correct for an iron spoon to be copper-plated ?
(a) Iron spoon (+), copper plate (-), Iron sulphate electrolyte
(b) Iron spoon (-), copper plate (+), Iron sulphate electrolyte
(c) Copper plate (-), Iron spoon (+), Copper sulphate electrolyte
(d) Copper plate (+), Iron spoon (-), Copper sulphate electrolyte

Q. State whether true or false :

If current is passed through copper sulphate solutions, copper gets deposited on the plate connected to the negative terminal of the battery.

Assertion: Upal observed that copper is deposited on the negative electrode connected to the terminal of the battery. Kavya performed the same experiment but she replaced the copper electrode with a carbon electrode and still observed copper is deposited over carbon rod.

Reason: Copper sulphate solution dissociates into copper and sulphate ions when electricity is passed through dilute copper sulphate solution and this free copper ions deposit on the carbon rod.
