Which method can be used to find out the 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 electrochemical cells, specifically by measuring the cell potential (E_cell) using a standard hydrogen electrode (SHE) as a reference. Here’s a step-by-step explanation of the method:

### Step-by-Step Solution:

1. **Set Up the Electrochemical Cell**:
- Use a conductivity cell with two electrodes. One electrode will be a standard hydrogen electrode (SHE), which has a standard reduction potential of 0 V.
- The second electrode will be the electrode of the species whose oxidizing or reducing strength you want to measure (let's call it E1).
