Unit 9: Acid/Base Study Guide (PART 2) -2017

Topics to review:

·  Arrhenius definition of an acid/base

·  Brønsted-Lowry definition of an acid/base

·  Lewis definition of an acid/base

·  Conjugate Acid-Base Pairs

·  Characteristics of acids and bases

·  Equilibriums with acids/bases

Practice Problems:

1.  Why is Arrhenius’s definition of a base inappropriate for ammonia (NH3)?

2.  In the reaction below, which reactant is acting like a Bronsted-Lowry acid? How can you tell?

3.  In the reaction below, which reactant is acting like a Bronsted-Lowry base? How can you tell?

4.  Write the reverse reactions for the model below and label the Bronsted-lowry acid and base for the reactants.

5.  Write the formula for the conjugate base for each of the following acids:

a)  H2SO4

b)  HCO3-

c)  HPO42-
