Question
Chapter 14.9, Problem 14.72QAP
Interpretation Introduction
Interpretation: Consider the buffer system of nitrous acid, HNO2, and its salt, NaNO2
a. The purpose of this buffer system is to:
1. Maintain [HNO2]
2. Maintain [NO2-]
3. Maintain pH
b. The weak acid is needed to
1. Provide the conjugate base
2. Neutralize added OH-
3. Provide the conjugate acid
c. If H3O+ is added, it is neutralised by
1. The salt
2. H2O
3. H3O+
d. When OH- is added, the equilibrium shift in direction of the:
1. Reactants
2. Product
3. Does not change
Concept introduction:
A buffer system is a solution that resists change in pH when acids or bases are added to it.
Buffer systems are made of either a weak acid and its salt or a weak base and its salt.
