Dissolve 6.05 g (6.3 ml, 0.05 mol) of dimethylaniline in 3.0 ml of glacial acetic acid, and add it with vigorous stirring to the suspension of diazotised sulphanilic acid. There are three main steps for writing the net ionic equation for Acetic acid and Sodium hydroxide. Sodium Nitrite Dangers You Can't Afford to Ignore - Dr. Axe sodium nitrite in aqueous acetic acid. Indeed, hypochlorite anions are slightly basic. The nitrosation of gramine, a tertiary amine alkaloid present in barley malt, was carried out by reaction with sodium nitrite in buffered acetic acid (pH 3.4) for 1 hr at room temperature.
