Which method can be used to find out strength of reductant/oxidant in a solution? Explain with an example.

Explanation

To determine the strength of a reductant or oxidant in a solution, we can use the method of measuring the electrode potential of the given species. Here’s a step-by-step explanation of how this method works, along with an example.

### Step 1: Understand Oxidants and Reductants
- **Oxidants (Oxidizing Agents)**: These are substances that gain electrons in a chemical reaction and are reduced.
- **Reductants (Reducing Agents)**: These are substances that lose electrons in a chemical reaction and are oxidized.

### Step 2: Use Electrode Potential
- The strength of an oxidant or reductant can be measured by determining the electrode potential of the species in question. This is done by connecting the redox couple of the species to a standard reference electrode, typically the Standard Hydrogen Electrode (SHE).
