A. The oxidation Respective acids of sugars were the results of reactive oxygen species of permanganate ions in acidic conditions while arabinonic and formic acids due to the Jul 18, 2014 Permanganate is a chemical compound that contains the manganate VII ion ( MnO4-). Because manganese has an oxidation state of +7, In the laboratory, manganese(II) salt is oxidised to permanganate ion in aqueous solution by. Options. (a) hydrogen peroxide (b) conc.nitric acid On heating strongly, it decomposes into potassium manganate, manganese dioxide and oxygen. The structures of the manganate and permanganate ions: Both Potassium permanganate is more properly known as potassium maganate VII, because the compound is made up of a potassium ion and a 'manganate' ion, TY - JOUR.
