![**Question:**
What is the pH of a solution of 0.29 M HCl?
**Answer Choices:**
- 0.38
- 0.53
- 0.29
- 0.15
**Explanation:**
To calculate the pH of a strong acid like hydrochloric acid (HCl), simply use the formula:
\[ \text{pH} = -\log[\text{H}^+] \]
For a strong acid like HCl that completely dissociates in water, the concentration of hydrogen ions \([\text{H}^+]\) is the same as the concentration of the acid.
Given:
- \([\text{HCl}] = 0.29 \, \text{M}\)
Calculate pH:
\[ \text{pH} = -\log(0.29) \approx 0.54 \]
Therefore, the closest answer choice is 0.53.](https://content.bartleby.com/qna-images/question/a0e64ef2-ef33-42d4-8972-9fbccb33a1ca/d4eb5f39-1574-471b-80ad-b82d88da8466/pknf7vw_processed.jpeg)
