Chemical Information
FooDB NamePotassium phosphate (K(H2PO4))
DescriptionMonopotassium phosphate, also known as MKP or potassium phosphoric acid, belongs to the class of inorganic compounds known as alkali metal phosphates. These are inorganic compounds in which the largest oxoanion is phosphate, and in which the heaviest atom not in an oxoanion is an alkali metal. Based on a literature review very few articles have been published on Monopotassium phosphate.
