Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Question

**Redox Reaction in Basic Solution**
The task is to complete and balance the following redox reaction occurring in a basic solution:

\[\text{Cr}_2\text{O}_7^{2-}(\text{aq}) + \text{Hg}(\text{l}) \rightarrow \text{Hg}^{2+}(\text{aq}) + \text{Cr}^{3+}(\text{aq})\]

**Explanation:**

- The dichromate ion (\(\text{Cr}_2\text{O}_7^{2-}\)) is typically reduced to chromium(III) ions (\(\text{Cr}^{3+}\)).
- Mercury (\(\text{Hg}\)) is oxidized to mercury(II) ions (\(\text{Hg}^{2+}\)).
- The reaction must be balanced for mass and charge, considering it is in a basic solution. This includes balancing oxygen with water (\(H_2O\)) and hydrogen with hydroxide (\(OH^-\)).
