Justification for type of information:
Data waiving
Reason: Other justification
Justification: Hydrolysis is not a relevant process for ammonium wolframate, as in principle, water acts as an oxidising agent with tungsten compounds (Lassner and Schubert, 1999). The behavior of the substance in water is more accurately examined through the Transformation/Dissolution testing protocol.
