Question

Consider a buffer solution whose acid component is nitrous acid, HNO2

a) what is a conjugate base component of this buffer?

b) write a reaction that takes place when a small amount of H3O+ is introduced to this buffer solution.

c) write a reaction that takes place when a small amount of OH- is introduced to this buffer solution

Answer 1

HNO2 --> H+ and NO2-

a)

then the conjugate base is NO2-

b)

H3O+ + NO2- --> HNO2 + H2O

c)

OH- + HNO2 --> H2O + NO2-
