Question

Which compounds are the Bronsted-Lowry bases in this equilibrium: `HC_2O_4^- + H_2BO_3^(-) rightleftharpoons H_3BO_3 + C_2O_4^(2-)`?

Answer 1

The base is the proton acceptor............

Explanation:

And thus in the given reaction, the oxalic acid salt is the acid, which means that `(HO)_2BO^(-)`, the boric acid salt, is the base............

`underbrace(""^(-)"O(O=)CC(=O)OH")_color(red)"the acid" + underbrace("(HO)"_2"BO"^(-))_color(blue)"the base"rarr^(-)"O(O=)CC(=O)O"^(-) +"B(OH)"_3`
