The equivalent weight of `MnSO_(4)` is half its molecular weight when it is converted to

Explanation

To solve the question, we need to determine the product formed when manganese sulfate (MnSO₄) is converted such that its equivalent weight becomes half of its molecular weight.

### Step-by-Step Solution:

1. **Understand Equivalent Weight**:
The equivalent weight of a substance is defined as the molecular weight divided by the number of electrons transferred in a reaction (valency change). Mathematically, it can be expressed as:
\[
\text{Equivalent Weight} = \frac{\text{Molecular Weight}}{\text{n-factor}}
