(i) Hydrogen fluoride is a weaker acid than hydrogen chloride in aqueous solution.
Or Which is a stronger acid in aqueous solution, HF or HCI ?
(ii) In aqueous solution, HI is a stronger acid than HCI ?
(iii) F atom is more electronegative than I atom, yet HF has lower acid strength than HI. Explain.

Explanation

To answer the questions step by step, let's break down each part of the problem:

### (i) Which is a stronger acid in aqueous solution, HF or HCl?

1. **Definition of Acid Strength**: Acid strength in aqueous solution is determined by the ability of the acid to dissociate and release H⁺ ions.

2. **Dissociation of HF and HCl**:
- HF dissociates as follows: HF ⇌ H⁺ + F⁻
