Consider the buffer system of nitrous acid, HNO2, and its salt, NaNO2.
2(aq) + H2O(l) h3O + (aq) + NO2− (aq)
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. The addition of H3O + is neutralized by:
1. the salt
2. H2O
3. OH−
d. When OH− is added, the equilibrium shifts in the direction of the:
1.reactants
2. products
3. does not change
