Web(a) Diazotization of Sulfanilic Acid. In a 50 mL Erlenmeyer flask dissolve, by carefully boiling, 1.1 g of sulfanilic acid in 13 mL of 2.5 % sodium carbonate solution. Cool the solution under the tap and add 0.5 g of sodium nitrite, and stir until it is dissolved. WebArenediazonium salts are easily prepared from arylamines (anilines) using a process called diazotization. The process involves dissolving the amine in a suitable acid, cooling in an ice bath to 0-5 o C, then adding sodium nitrite (NaNO 2) solution. The acid reacts with the NaNO 2 to form nitrous acid (HNO 2), which then reacts with the arylamine to form the …
