What is Potassium hypomanganate?
'''Potassium hypomanganate''' is a [[chemical compound]]. It contains [[potassium]] and [[hypomanganate]] [[ion]]s. It is a bright blue solid. It is unstable and rare. It can be made several ways: [[reduction (chemistry)|reduction]] of [[potassium permanganate]] with [[potassium sulfite]]; reduction of [[potassium manganate]] with [[hydrogen peroxide]] and [[potassium hydroxide]]; and [[disproportionation]] when [[manganese dioxide]] is dissolved in [[potassium hydroxide]]. It disproportionates into potassium manganate and manganese dioxide easily. Only a strong [[base (chemistry)|base]] can stop it from disproportionation. ==Related pages== *[[Sodium manganate]] *[[Sodium permanganate]] [[Category:Potassium compounds]] [[Category:Manganese compounds]]
