MCQ
Which of the following can act both as Bronsted acid and Bronsted base
- A$C{l^ - }$
- ✓$HCO_3^ - $
- C${H_3}{O^ + }$
- D$O{H^ - }$
✓
Answer
Correct option: B.
$HCO_3^ - $
(b)Those substance accept the proton are called Bronsted base and which is donate the proton are called Bronsted acid.
$HCO_3^ - + {H^ + } $ $ \rightleftharpoons $ $ {H_2}C{O_3}$ Bronsted base.
$HCO_3^ - $ $ \rightleftharpoons $ $ {H^ + } + CO_3^{2- }$ Bronsted acid.
