Calculate the n- factor of reactants in the given chemical changes?
(c ) `S_(2)O_(3)^(2-) overset("alkaline")rarrSO_(4)^(2-)`

Explanation

To calculate the n-factor of the reactant \( S_2O_3^{2-} \) in the reaction where it is converted to \( SO_4^{2-} \) in an alkaline medium, we will follow these steps:

### Step 1: Identify the oxidation states of sulfur in the reactant and product.
- In \( S_2O_3^{2-} \):
Let the oxidation state of sulfur be \( x \).
The formula for the oxidation state can be set up as follows:
\[
2x + 3(-2) = -2
