Title: An aqueous solution is prepared by dissolving 0.23 mol of nitrous acid and 0.27 mol of sodium ... Post by: yexiu on Jun 27, 2021 An aqueous 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.
▸ H2O ▸ H3O+ ▸ nitrite ion ▸ nitrous acid ▸ This is a buffer solution: the pH does not change at all upon addition of acid or base. Title: An aqueous solution is prepared by dissolving 0.23 mol of nitrous acid and 0.27 mol of sodium ... Post by: Aizhan on Jun 27, 2021 Content hidden
