According to the Arrhenius definitions of acids and bases, choose the bases from the list of acids and bases. Check all that apply.
NH4+HPO42-HPO42– H2PO4–
NH4+ NH3HPO42–H2PO4–
H2SHCO3-HS–H2CO3
H2SHCO3-HS–H2CO3
Fe3+H2OFe(H2O)63+
N(CH3)3BH3(CH3)3N:BH3
Explain how water behaves in this reaction. Which definition of acids and bases would you apply?

Water behaves as a base in this reaction. The Brønsted-Lowry definition should be applied because the reaction involves the transfer of a proton (H+) from carbonic acid (H2CO3) to water (H2O). Since a Brønsted-Lowry base is defined as a proton acceptor and water gains a proton to form H3O+, it acts as a base.
