Textbook Question
Chapter 12, Problem 5Q
Nitrous acid (HNO2) has a Ka value of 4.0 × 10 4,
which corresponds to a pKa of 3.39.
- a. What salt would you use to prepare a good buffer solution with nitrous acid?
- b. If NaOH were added to the buffer solution, what would it react with?
- c. Compare how the pH would change if 0.05 moles of NaOH were added to the buffer solution compared to a container with just water.

Why are the carboxylic acid groups of the amino acids more acidic (pKa - 2) than a carboxylic acid such as acetic acid (pKa = 4.76)?
we use the algebra method to find the pka values of 3.954 and the graphical method to find the pKa is 3.9533, with an accepted value of 4.0
Compare your algebraically and graphically determined pK values. Which method was moreaccurate? Why would you expect these values to be very close to each other?
What is the pKa of nitrous acid; Ka = 4.5 × 10–5 ?
