Which of the following aqueous solution will have pH less than 7.0?

Options

  1. AKNO 3
  2. BNaOH
  3. CFeCl 3
  4. DNaCN

Correct answer

C. FeCl 3

Step-by-step solution

FeCl 3 is a salt of weak base, Fe(OH) 3 and strong acid, HCl , so FeCl 3 solution is acidic in nature. In other words, Fe 3+ hydrolyze, but Cl − does not.
