Q: Which of the following acids is a weak acid?
Solution:
Acetic acid (CH3COOH) is a weak acid, while HCl, H2SO4, and HNO3 are strong acids.
Steps: 6
Show Steps
Step 1: Understand what an acid is. Acids are substances that can donate protons (H+) in a solution.
Step 2: Learn the difference between strong acids and weak acids. Strong acids completely dissociate in water, while weak acids do not.
Step 3: Identify the acids in the question: HCl, H2SO4, HNO3, and acetic acid (CH3COOH).
Step 4: Determine the strength of each acid: HCl, H2SO4, and HNO3 are strong acids because they fully dissociate in water.
Step 5: Recognize that acetic acid (CH3COOH) is a weak acid because it only partially dissociates in water.
Step 6: Conclude that the weak acid among the options is acetic acid (CH3COOH).
