Is HI stronger than HCl?
Understand the Problem
The question is asking whether hydrogen iodide (HI) is a stronger acid than hydrochloric acid (HCl). This involves comparing their acid strengths, typically measured by their dissociation in water and the resulting pH levels.
Answer
HI is stronger than HCl.
The final answer is HI is stronger than HCl.
Answer for screen readers
The final answer is HI is stronger than HCl.
More Information
HI is a stronger acid than HCl primarily because the H–I bond is weaker and dissociates more easily than the H–Cl bond, which makes it easier for HI to donate H+ ions.
Tips
A common mistake is to assume bond strength only depends on electronegativity differences. Bond dissociation energy is also a crucial factor in determining acid strength.
