An aqueous solution of salt is alkaline. This shows that salt is made from:
- A. a strong acid and a strong base
- B. a strong acid and a weak base
- C. a weak acid and a weak base
- D. a weak acid and a strong base
Step-by-step solution
An alkaline (basic) solution results from the hydrolysis of the anion of a weak acid, which produces OH⁻ ions. This occurs when the salt is formed from a weak acid and a strong base, as the cation from the strong base does not hydrolyze significantly.
