Have a 20.00 mL sample of 0.10 M of nitrous acid,
HNO2(aq).
Is this a strong or weak acid? Explain how you know.
Consider the interaction of nitrous acid with water.
(a), Identify the acid, base, conjugate acid and conjugate
base in this reaction?
(b) Write a balanced chemical equation for
this reaction.
This acid is titrated with 0.40 M sodium hydroxide, NaOH.
(a) Calculate the initial pH of the acid prior to titrating.
(b) Calculate the pH at equivalence point.
(c) Calculate the pH after 20.00 mL of NaOH is added.
(d) Would a buffer ever form in this titration? Explain?
