Post by: jkaur2017 on Oct 13, 2018 A solution is prepared by dissolving 0.23 mol of nitrous acid and 0.27 mol of sodium nitrite in water sufficient to yield 1.00 L of solution. The addition of 0.05 mol of HCl to this buffer solution causes the pH to drop slightly. The pH does not decrease drastically because the HCl reacts with the __________ present in the buffer solution. The Ka of nitrous acid is 1.36 10-3.
A) H2O B) H3O+ C) nitrite ion D) nitrous acid E) This is a buffer solution: the pH does not change upon addition of acid or base. Title: A solution is prepared by dissolving 0.23 mol of nitrous acid and 0.27 mol of sodium nitrite in ... Post by: gugu123 on Oct 13, 2018 Content hidden
