Question

The reaction is observed to be product favored with a K> 1.
HSO3- (aq) + HPO42- (aq) = SO32- (aq) + H2PO4- (aq)
What is the strongest base present in this reaction?
OH P04- (aq)
OHSO3- (aq)
OSO32- (aq)
OHPO42- (aq)​

Answer 1

Answer:

First of all we need to figure out what are the bases present in this reaction.

according to bronsted Lowry concept, the molecule which accepts electron act as a base

So in the above reaction bases are

HPO42- and SO32-

as the product is favoured means reactant is accepting electron more readily.

hence the strongest base is HPO42-

Hope it helps..
