What is Sodium phosphate?
'''Sodium phosphate''' is a group of [[chemical compounds]]. The [[phosphate]] atom can hold three other atoms. They can be three hydrogen ([[phosphoric acid]]), two hydrogen and one sodium(sodium dihydrogen phosphate), one hydrogen and two sodium (disodium hydrogen phosphate), or three sodium (trisodium phosphate). ==Sodium dihydrogen phosphate== '''Sodium dihydrogen phosphate''', also known as '''monosodium phosphate''', is a chemical compound with the formula NaH<sub>2</sub>PO<sub>4</sub>. It is [[acid]]ic. It is used in some [[baking powder]]s. It is used as a [[laxative]] or a pH buffer (something that keeps a chemical from getting more acidic or basic). It is made by reaction of a little [[sodium hydroxide]] with [[phosphoric acid]]. ==Disodium hydrogen phosphate== '''Disodium hydrogen phosphate''', also known as '''disodium phosphate''' is a chemical compound with the formula Na<sub>2</sub>HPO<sub>4</sub>. It is about neutral (not acidic or basic). It is used to prevent clumping in foods. It is made by reaction of some [[sodium hydroxide]] with [[phosphorus]]. ==Trisodium phosphate== [[File:Trisodium phosphate hydrate.jpg|thumb|Trisodium phosphate]] '''Trisodium phosphate''', also known as '''sodium phosphate''', is a chemical compound with the formula Na<sub>3</sub>PO<sub>4</sub>. It is [[base (chemistry)|basic]]. It formerly was used in detergents, but the phosphate fueled algal blooms. It is made by combining [[sodium hydroxide]] and [[phosphoric acid]]. ==Related pages== *[[Phosphite]] *[[Sodium phosphite]] *[[Hypophosphite]] [[Category:Phosphorus compounds]] [[Category:Sodium compounds]]
