Question

Quizplus · Accepted Answer

In the given reaction, the acid is the species which donates a proton or H+ ion. Here, the aqueous solution of sulfuric acid (HSO4-) donates a proton to the aqueous solution of carbonate ion (CO32-), forming aqueous solution of hydrogen carbonate ion (HCO3-) and sulfate ion (SO42-). Therefore, the acid in the given reaction is HSO4- (or sulfuric acid). Choice E includes HSO4- in its formula.
