Disodium Phosphate
<p><b >Disodium hydrogen phosphate</b> (Na<sub >2</sub>HPO<sub >4</sub>) is a <a href="http://en.wikipedia.org/wiki/Sodium" title="Sodium" >sodium</a> <a href="http://en.wikipedia.org/wiki/Salt_(chemistry)" title="Salt (chemistry)" >salt</a> of <a href="http://en.wikipedia.org/wiki/Phosphoric_acid" title="Phosphoric acid" >phosphoric acid</a>. It is a white powder that is highly <a href="http://en.wikipedia.org/wiki/Hygroscopic" title="Hygroscopic" class="mw-redirect" >hygroscopic</a> and water soluble.<sup id="cite_ref-0" class="reference" ><a href="http://en.wikipedia.org/wiki/Disodium_phosphate#cite_note-0" >[1]</a></sup> It is therefore used commercially as an anti-caking additive in powdered products. It is also known as disodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic. It is commercially available in both the hydrated and anhydrous forms.<sup id="cite_ref-1" class="reference" ><a href="http://en.wikipedia.org/wiki/Disodium_phosphate#cite_note-1" >[2]</a></sup> pH of disodium hydrogen phosphate water solution is between 8.0 and 11.0.
