Question:
Explain the difference between a strong acid and a weak acid. How does the pH of a solution change when a strong acid is added compared to a weak acid?
Explain the difference between a strong acid and a weak acid. How does the pH of a solution change when a strong acid is added compared to a weak acid?
Show Hint
A strong acid dissociates completely in water, while a weak acid only dissociates partially, resulting in different pH levels for the same concentration.

- A strong acid dissociates completely, while a weak acid only partially dissociates.
- Strong acids have higher pH than weak acids.
- Weak acids produce fewer hydronium ions than strong acids.
- Both A and C are correct.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
A strong acid dissociates completely in water, releasing a higher concentration of hydronium ions (\( \text{H}_3\text{O}^+ \)) than a weak acid. This results in a lower pH for strong acids. A weak acid only partially dissociates, meaning it produces fewer hydronium ions, leading to a higher pH compared to a strong acid of the same concentration.
