The $CH_3COO^-$ ion is a.......

Given below are two statements,one is labelled as Assertion $A$ and the other is labelled as Reason $R:$
Assertion $A :$ The amphoteric nature of water is explained by using Lewis acid/base concept.
Reason $R :$ Water acts as an acid with $NH_{3}$ and as a base with $H_{2}S$.
In the light of the above statements,choose the correct answer from the options given below:

Identify the conjugate bases of $H_3PO_3$ and $H_2SO_4$ respectively from the following.

Select the reaction which will be favoured in the forward direction.

The conjugate base of the strong acid in the reaction $CH_3COOH + HCl \rightleftharpoons Cl^{\Theta} + CH_3COOH_2^{\oplus}$ is:

The conjugate acid of $NH_2^-$ is
