Chapter 3, Problem 1LGP

List all the chemical species likely to be present at the end of the reaction but before adding aqueous ${\text{NaHCO}}_3$. Note that the ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ was not consumed (since it is a catalyst), and is thus still available to donate a proton to atoms that can be protonated.
