WebSodium bisulfite adds reversibly to aldehydes and a few ketones to give bisulfite addition products (see Fig. P19.42). (a) Write a curved-arrow mechanism for this addition reaction; assume water is the solvent. (b) The reaction can be reversed by adding either $\mathrm{H}_{3} \mathrm{O}^{+}$ or - OH. Explain this observation using Le Châtelier ... WebSodium bisulfite (NaHSO 3) in water treatment is usually used for chemical binding of oxygen in the treated water. Sodium bisulfite attaches oxygen and becomes sodium bisulfate. ... Most likely, the pH value will be below 4. Therefore, the addition of alkali to the resulting solution will be required to bind excess acidity. But the final pH of ...
