Give the conjugate acids of `OH^(-), HSO_4^(-)` and `NH_3`.

Explanation

To find the conjugate acids of the given bases, we need to understand the concept of conjugate acids and bases. A conjugate acid is formed when a base accepts a proton (H⁺ ion).

### Step-by-Step Solution:

1. **Identify the bases**: The bases we need to find conjugate acids for are:
- OH⁻ (hydroxide ion)
- HSO₄⁻ (hydrogen sulfate ion)
- NH₃ (ammonia)
