Differentiate between the terms strong electrolyte and weak electrolyte. (stating any two differences)

Name:

(i) the product formed at the anode – during electrolysis of acidified water using platinum electrodes.

(ii) the metallic ions that should be present – in the electrolyte when an article made of copper is to be electroplated with silver.

During purification of copper – State:

(i) The anode used

(ii) The electrolyte used.

Write the equation taking place at the anode in the above.

Write equations for the reactions taking place at the two electrodes during the electrolysis of:

(i) Acidified CuSO₄ solution with copper electrodes.

(ii) Molten PbBr₂ with inert electrodes. (mention clearly the name of the electrode in each case)
