Ammonium dihydrogenphosphate
Chemically pure NH<sub>4</sub>H<sub>2</sub>PO<sub>4</sub> was used. (NH<sub>4</sub>)<sub>2</sub>H<sub>2</sub>P<sub>2</sub>O<sub>7</sub> was prepared by heating (NH<sub>4</sub>)<sub>4</sub>P<sub>2</sub>O<sub>7</sub> at 110°C for 46 hours. The product contained 91.9% (NH<sub>4</sub>)<sub>2</sub>H<sub>2</sub>P<sub>2</sub>O<sub>7</sub> and 4.4% NH<sub>4</sub>H<sub>2</sub>PO<sub>4</sub>. Paper chromatography<sup>2</sup> showed the absence of any more condensed polyphosphates.
