how is the loss of copper ions from copper sulphate solution compenstated

Open in App

Solution

When electric current is passed through copper sulphate solution, the copper sulphate breaks up into copper and sulphate ions. The free copper gets drawn to the plate connected to the negative terminal of the battery and gets deposited on that plate. From the other plate, an equal amount of copper gets dissolved in the solution this is how The loss of copper from solution is compensated and the process goes on.

ions?

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.

Q. Assertion :The colour of copper sulphate solution change when an iron nail is dipped in it. Reason: When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate.

Q. Assertion :Copper sulphate solution conducts electricity because of dissociated ions. Reason: Copper metal conducts electricity because of its valence shell electrons.
