An aqueous solution of salt is alkaline. This shows that salt is made from:

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.
