Answer 2

Answer : Option D)
`H_(2)BO_(3)^(-) and C_(2)O_(4)^(2-)`.

Explanation : The acid base theory of Bronsted-Lowry, stated the definition of acids and bases on the basis of conjugated.

The fundamental concept of this theory states that when an acid and a base reacts with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchanging the proton.

So, in the given reaction;

`HC_(2)O_(4)^(-) + H_(2)BO_(3)^(-) <---> H_(3)BO_(3) + C_(2)O_(4)^(2-)`

It is firstly observed that the species
`H_(2)BO_(3)^(-)` is accepting a proton from the acid, therefore this is one of the bases.

Secondly,
`C_(2)O_(4)^(2-)` accepts the proton and forms the reactant again in the reversible reaction.

Therefore, these are the correct options.

`H_(2)BO_(3)^(-) and C_(2)O_(4)^(2-)`
