An aqueous solution of `NaCl` is electrolysed with inert electrodes. Write the equations for the reactions taking place at cathode and anode. What happens if `AgNO_(3(aq.))` is used instead of `NaCl`?

Text Solution

AI Generated Solution

To solve the question, we will break it down into two parts: the electrolysis of an aqueous solution of NaCl and the electrolysis of an aqueous solution of AgNO3. ### Part 1: Electrolysis of Aqueous NaCl 1. **Identify the electrodes**: In this case, we are using inert electrodes, which do not participate in the reaction but allow the passage of current. 2. **Anode Reaction**: At the anode, oxidation occurs. In the case of NaCl, water is oxidized to produce oxygen gas. The half-reaction can be written as: \[ ...
