Question

OH- (aq) + HCO3- (aq) --- H2O (l) + CO32-(aq)
If OH is considered base 1, the right conjugates are..

Answer 1

Answer: The right conjugate of $OH^-$ is $H_2O$

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.

For the given chemical equation:

$OH^-(aq)+HCO_3^-(aq)\rightleftharpoons H_2O(l)+CO_3^{2-}(aq)$

Here, $OH^-$ is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms $H_2O$ which is a conjugate acid.

Thus the right conjugate of $OH^-$ is $H_2O$
