Question
Which of the following is considered weak acid?
- Sulphuric acid
- Nitric acid
- Phosphoric acid
- All of the above
Hint:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution.
The correct answer is: Phosphoric acid
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid.
Phosphoric acid is a weak acid.
