Final answer:
The reaction between HSO4- and NH3 produces SO4^2- and NH4^+.
Step-by-step explanation:
The reaction between HSO4- and NH3 can be represented by the equation HSO4- + NH3 → SO42- + NH4+. In this reaction, the HSO4- ion (a strong acid) reacts with the NH3 molecule (a weak base) to form the SO42- ion and the NH4+ ion.
