WebAmino acids contain a free amino group and a free carboxylic acid group that react together with ninhydrin to produce a coloured product. When an amino group is attached to the first, or alpha, carbon on the amino acid’s carbon chain, the amino group’s nitrogen atom is part of a blue-purple product, as shown in Equation 2. WebNitrous acid (molecular formula H N O. 2) is a weak and monoprotic acid known only in solution, in the gas phase and in the form of nitrite ( NO−. 2) salts. [2] Nitrous acid is used to make diazonium salts from amines. The resulting diazonium salts are reagents in azo coupling reactions to give azo dyes .
