Q
Q: Which of the following is a characteristic of a weak acid?
Solution:
Weak acids have a high pKa value, indicating they do not completely dissociate in solution.
Steps: 4
Show Steps
Step 1: Understand what an acid is. An acid is a substance that can donate protons (H+ ions) in a solution.
Step 2: Learn about strong and weak acids. Strong acids completely dissociate in water, meaning they break apart into ions fully. Weak acids do not.
Step 3: Know what pKa means. pKa is a measure of how easily an acid donates protons. A higher pKa value means the acid is weaker.
Step 4: Identify the characteristic of weak acids. Weak acids have a high pKa value because they do not fully dissociate in solution.
