Which among the following cannot act as both bronsted acid and base
1.h2o
2.nh3
3.co2
4.hso4-

Answer 1

$CO_2$ cannot act as both bronsted acid and base.

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

1. $H_2O\rightarrow OH^{-}+H^+$

Here,$H_2O$ is loosing a proton, thus it is considered as an acid.$H_2O+H^+\rightarrow H_3O^+$

$H_2O$ is gaining a proton, thus it is considered as a base.

2. $NH_3+H^+\rightarrow NH_4^+$

$NH_3$ is gaining a proton, thus it is considered as a base. $NH_3\rightarrow NH_2^{-}+H^+$

Here, $NH_3$ is loosing a proton, thus it is considered as an acid.

3. $CO_2$ can not gain or lose $H^+$ and thus cannot act as both bronsted acid and base.

4. $HSO_4^-\rightarrow SO_4^{2-}+H^+$

Here, $HSO_4^-$ is loosing a proton, thus it is considered as an acid.

$HSO_4^-+H^+\rightarrow H_2SO_4$

$HSO_4^-$ is gaining a proton, thus it is considered as a base.

Answer 2

$CO_2$ cannot act as both bronsted acid and base.

Explanation:

• A bronsted acid is 'any species' that will distribute a proton ( positive charge).

• A bronsted base is 'any species' that will receive a proton, which is in requirement of a lone pair of electrons to bond with.

• In this case, $CO_2$ doesn't act as bronsted acid as it cannot donate a proton that is $H^+$ ion.

• And also it doesn't act as a bronsted base as it cannot accept a proton, a  positive charge $H^+$ ion.
