Using the Arrhenius concept of acids and bases, identify the Arrhenius acid and base in each of the following reactions:
2KOH(aq) + H2SO4(aq) ---> K2SO4(aq) + 2H2O(l)
NH3(g) + HCl(g) ---> NH4Cl(s)
The Arrhenius Definition of Acids and Bases:
Acid: a substance that produces H+ ions in aqueous solution
Base: a substance that produces OH- ions in aqueous solution
