• Write the equation for the dissociation of
KOH.
– KOH  K+ + OH-
• Identify each reactant in the following
equation as an acid or a base according
to the Brønsted-Lowry Model.
– HNO3 + H2O  H3O+ + NO3– H2O + CH3COO-  CH3COOH + OH-
• What does it mean to be amphoteric?
• Write equations showing that the
hydrogen phosphate ion (HPO42- ) is
amphoteric.
• Write the formula for the conjugate base
of each of the following Brønsted-Lowry
Acids.
a. HCO3b. HI
CO32I-
• Why was the Brønsted-Lowry model of
acids and bases needed?
• The substance NaOH is classified as a
base by both Arrhenius and BrønstedLowry. Using your knowledge of
chemistry explain why NaOH is a base in
each of the models.
• Using your knowledge of the BrønstedLowry Model, complete the following
equation:
OH- + HPO42- 
