Chemical Information
FooDB NameSodium phosphate (Na3PO4)
DescriptionSodium phosphate (Na3PO4), also known as sodium phosphate or NA3PO4, 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. Sodium phosphate (Na3PO4) is a moderately acidic compound (based on its pKa). Sodium phosphate (Na3PO4) is an odorless tasting compound.
