So yes, it is a weak acid (NH4+) and weak base (NO2-). But you have to compare the Ka and Kb for these species before making a judgement!
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 .
