What is Sodium manganate?
'''Sodium manganate''' is a [[chemical compound]]. Its chemical formula is Na<sub>2</sub>MnO<sub>4</sub>. It contains [[sodium]] and [[manganate]] [[ion]]s. It is a bright green solid at 25 degrees Celsius at [[standard atmosphere]] (a pressure). It cannot be made by reacting [[manganese dioxide]] with [[sodium hydroxide]], like [[potassium manganate]] is made. It is made by reacting hot [[sodium hydroxide]] with [[sodium permanganate]]. This releases oxygen and makes sodium manganate. It is more expensive than potassium manganate because it is harder to make. ==Related pages== *[[Manganese(II) oxide]] *[[Manganese(VII) oxide]] *[[Potassium permanganate]] [[Category:Sodium compounds]] [[Category:Manganates]] {{chem-stub}}
