Find oxidation state of sulphur in sulphuric acid `(H_2SO_4)`.

Explanation

To find the oxidation state of sulfur in sulfuric acid (H₂SO₄), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: We are working with sulfuric acid, which has the chemical formula H₂SO₄.

2. **Understand the Neutral Molecule Rule**: The overall charge of a neutral molecule is zero. Since H₂SO₄ is neutral, the sum of the oxidation states of all atoms in the molecule must equal zero.
