Give the conjugate acid of (i)`CO_3^(2-)` , (ii)`HCO_3^- `, (iii)`I^-` , (iv)`HSO_4^-` , (v) `OH^-` , (vi)`NH_3`.

Explanation

To find the conjugate acids of the given species, we need to understand that a conjugate acid is formed when a base accepts a proton (H⁺). Here’s how to determine the conjugate acids for each of the given species step by step:

### Step-by-Step Solution:

1. **Conjugate Acid of \( \text{CO}_3^{2-} \)**:
- The carbonate ion (\( \text{CO}_3^{2-} \)) can accept a proton (H⁺).
- When it accepts a proton, it becomes \( \text{HCO}_3^{-} \).
- **Conjugate Acid**: \( \text{HCO}_3^{-} \)
