	~~'''Disodium hydrogen phosphate'''~~ is the ~~[[inorganic compound]] with the formula Na<sub>2</sub>HPO<sub>4</sub>~~.

	~~==Acid-base properties==~~
	~~The [[pH]] of disodium hydrogen phosphate water solution is between 8.0 and 11.0, meaning it is [[base (chemistry)\|basic]]:~~

	~~:H<sub>3</sub>PO<sub>4</sub><sup>2-</sup> + 2 NaOH → HNa<sub>2</sub>PO<sub>4</sub> + 2 H<sub>2</sub>O~~

	~~Industrially It is prepared~~ in a two-step process by treating [[dicalcium phosphate]] with phosphoric acid, which precipitates [[calcium sulfate]]:<ref name=Ullmann>Klaus Schrödter, Gerhard Bettermann, Thomas Staffel, Friedrich Wahl, Thomas Klein, Thomas Hofmann "Phosphoric Acid and Phosphates" in ''Ullmann’s Encyclopedia of ~~Industrial Chemistry'~~' ~~2008, Wiley-VCH, Weinheim. {{DOI\|10.1002/14356007~~.~~a19_465.pub3}}~~<~~/ref~~>

	~~In the second step, the resulting solution of monosodium phosphate is partially neutralized~~:
	~~:NaH<sub>2</sub>PO<sub>4</sub> + NaOH → HNa<sub>2</sub>PO<sub>4</sub> + H<sub>2</sub>O~~

	~~==Uses==~~
	It is used as an in conjunction with [[trisodium phosphate]] in foods and water treatment. In foods, it is used to adjust pH. Its presence prevents coagulation in the preparation of condensed milk. Similarly, it is used as an anti-caking additive in powdered products.<ref>[http://~~www~~.~~sciencelab~~.~~com~~/~~msds~~.php?~~msdsId~~=~~9925023 MSDS]<~~/~~ref> It is used in desserts and puddings, e.g. [[Cream of Wheat]] to quicken cook time, and Jell~~-~~O Instant Pudding for thickening.

	~~Heating solid disodium phosphate gives the useful compound [[tetrasodium pyrophosphate~~]]:
	~~:2 HNa<sub>2</sub>PO<sub>4</sub> → Na<sub>4</sub>P<sub>2</sub>O<sub>7</sub> + H<sub>2</sub>O~~

	~~Monobasic and dibasic sodium phosphate are used as a saline laxative to treat constipation or to clean the bowel before a colonoscopy.<ref>[http://wishardhealth.kramesonline.com/Medications/26~~,~~1558]</ref>~~
