The reaction of ammonium metatungstate ((NH₄)₆H₂W₁₂O₄₀-xH₂O) with ammonia (NH₃-H₂O) does not directly result in a significant chemical change because both contain the ammonium ion (NH₄ ⁺). However, ammonium metatungstate may undergo decomposition if subjected to certain conditions, such as heat and possibly the presence of a catalyst, but this is not a direct reaction with ammonia.
It is worth noting, however, that while direct reaction of ammonium metatungstate with ammonia is uncommon, tungstic acid (H₂WO₄) can react with ammonia to form ammonium tungstate (e.g., (NH₄)₂WO₄). This reaction is a typical acid-base reaction in which tungstate acts as the acid and ammonia acts as the base.
The equation for the reaction between tungstic acid and ammonia:
H₂WO₄ + 2NH₃-H₂O → (NH₄)₂WO₄ + 2H₂O
This reaction shows that tungstic acid reacts with ammonia to form ammonium tungstate and water. However, there is no clear chemical reaction equation for the direct reaction between ammonium metatungstate and ammonia because the two do not readily react significantly under conventional conditions.
Ammonium metatungstate and ammonia do not react directly and significantly under conventional conditions. However, tungstic acid and ammonia can react to form ammonium tungstate and water. If a specific tungsten compound is to be obtained from ammonium metatungstate, it may be necessary to decompose the ammonium metatungstate by other methods, such as heating.
