A bioengineering student needs to prepare a pH = 3.00 buffer solution for cell culture. He starts from 1.25 L of a 1.00 M solution of nitrous acid (HNO2) and any amount his need of sodium nitrite (NaNO2).
(a) What is the pH of the nitrous acid solution prior to adding sodium nitrite?
(b) How many grams of sodium nitrite should be added to prepare the buffer solution? Neglect the small volume change that occurs when the sodium benzoate is added.
