Like water, ammonia (NH3) is an amphoteric substance that can be used as a solvent for acid base reactions. The phase label (am) means solvated by ammonia (ammoniated). Which statement is correct, extrapolating from your knowledge of acid base reactions in water ?
- Auto-ionization of ammonia is described by
\(2 \mathrm{NH}_{3}(I) \rightleftharpoons \mathrm{NH}_{4}^{+}(\mathrm{am})+\mathrm{NH}_{2}^{-}(\mathrm{am})\) - The strongest acid that can exist in ammonia solution is H3O+ (am).
- The strongest base, which can exist in ammonia solution, is \(\mathrm{NH}_{4}^{+}\)(am).
- The addition of an acid to an ammonia solution will increase the concentration of NH2– (am).
Answer
(A) Auto-ionization of ammonia is described by 2 NH _ 3 (I) NH _ 4 ^ + ( am )+ NH _ 2 ^ - ( am )
