Conditions:
Composition and temperature.
Compiler:
Methodology:
The only information given is that a self-constructed rotating furnace was used.
Sample Information:
- No information is given.
Measurement Errors:
Ambient temperature: No information is given. The compiler estimates the reproducibility of the temperature measurement to be ±3°C.
System Components:
- Diammonium hydrogenphosphate, $\ce{ (NH4)2HPO4 }$; [7783-28-0] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook

(a) These values were calculated by the compiler. The NH3 content was taken as the starting point in these calculations.
(b) These are the results of repeated observations.
