Question
When a solution containing zinc ions and silver ions is electrolysed, silver is deposited at cathode. Why?
Solution
Answer:
The discharge (reduction) potential of silver is less than that of zinc.
This is because these metals are less reactive than hydrogen and are lower down in the reactivity series. Reactive ions stay in solution and do not form atoms because they are more stable than the atoms.
