 Molecular formula：MnO2
Nature:
Chemistry manganese dioxide
Is black or gray powder with no shape, it could not
dissolve in water and nitric acid, it could dissolve
in hydrochloric acid and oxide and oxalic acid. It will
send out oxygen and form manganese sulphuric acid in
hot sulphuric acid, it could dissolve with alkali and
oxidant and form manganese acid salt. Chemistry manganese
dioxide have high adsorption and oxidation, it is a
kind of strong oxidant.
Use:
Chemistry manganese dioxide is mainly used in the
producing of dry cell of manganese series, used as aoganic
synthesis oxidant, as the raw material of solid electrolysis
condenser, printing and dyeing, bleaching, otaining
oxygen from smoke.
