When aqueous solutions of borax is acidified with HCl , we get

Options

  1. AB 2 H 6
  2. BH 3 BO 3
  3. CB 2 O 3
  4. DAll of these

Correct answer

B. H 3 BO 3

Step-by-step solution

When aqueous solution of borax Na 2 B 4 O 7 is acidified with HCl , we get H 3 BO 3 and NaCl as follows Na 2 B 4 O 7 Borox + 2 HCl + 5 H 2 O ⟶ 2 NaCl + 4 H 3 BO 3 Boric   acid Boric acid is not a proticacid it does not give H + ion accepts a pair of electrons and acts as a Lewis acid.
