### Question 16: Identifying Weak Acids

**Question:**
Which of the following are weak acids?

**Options:**
- HF, HBr
- HI, HNO₃, HBr
- HI, HF
- HF, H₃PO₄

**Correct Answer:**
- HF, H₃PO₄

**Explanation:**
This question tests the ability to distinguish between strong and weak acids. Weak acids do not completely dissociate in water. In the given options:
- **HF (Hydrofluoric acid)**: Known to be a weak acid as it does not fully ionize in solution.
- **H₃PO₄ (Phosphoric acid)**: Another example of a weak acid due to its partial ionization in solution.

### Additional Context:
Understanding the difference between strong and weak acids is crucial in chemistry, particularly in equilibrium and reaction predictions. Strong acids like HBr, HI, and HNO₃ fully dissociate in water, while weak acids only partially dissociate.
