Acids and Bases. To minimize the formation of high boilers (such as diisophorone and its cyano derivatives), the catalyst must be neutralized with an acid just at the point where the HCN has fully reacted, to eliminate cyanide ion, primarily in the form of LiCN, and free base (LiOH). Remember that H+ and H 3O + are equivalent. Certain salts will also affect the acidity or basicity of aqueous solutions because some of the ions will undergo hydrolysis, just like NH 3 does, to make a basic solution. Acid salts contain a hydrolyzable proton in the cation, anion, or both; for instance, the salt ammonium bisulfate (NH 4 HSO 4) contains an acidic proton in both the cation and the anion. NH4+ + … The equation for the dissociation of acetic acid, for example, is CH3CO2H + H2O ⇄ CH3CO2− + H3O+.
