Part A

Which acid is the best choice to create a buffer with pH= 3.16? (Answer was nitrous acid (HNO2), pKa=3.34, I think it's needed for the next part)

Part B

If you have 500 mL of a 0.10 M solution of the acid, what mass of the corresponding sodium salt of the conjugate base do you need to make the buffer with a pH of 3.16 (assuming no change in volume)?
