Question

In the following reaction HCO3-+H2Oleftharpoons CO32 -+H3O+ Which two substances are Bronsted base? (A) CO32 - and H3O+ (B) HCO3- and H3O+ (C) HCO3- and CO32 - (D) CO32 - and H2O

Here CO32 - and H2O are Bronsted bases as water accept H+ and CO32 - is the conjugate base of HCO3- and as the reaction is reversible so CO32 - is accepting H+ also. HCO3-+H2O leftharpoons CO32 -+H3O+

Q. In the following reaction

$H C O_{3}^{-} + H_{2} O ⇌ C O_{3}^{2 -} + H_{3} O^{+}$

Which two substances are Bronsted base?

$C O_{3}^{2 -}$ and $H_{3} O^{+}$

$H C O_{3}^{-}$ and $H_{3} O^{+}$

$H C O_{3}^{-}$ and $C O_{3}^{2 -}$

$C O_{3}^{2 -}$ and $H_{2} O$

Here $C O_{3}^{2 -}$ and $H_{2} O$ are Bronsted bases as water accept $H^{+}$ and $C O_{3}^{2 -}$ is the conjugate base of $H C O_{3}^{-}$ and as the reaction is reversible so $C O_{3}^{2 -}$ is accepting $H^{+}$ also.

$H C O_{3}^{-} + H_{2} O ⇌ C O_{3}^{2 -} + H_{3} O^{+}$
