What is oxidation state of oxygen in water.hydrogen peroxide.oxygen gas.in oxyfluorides

Answer»

Answer:

In a PEROXIDE ion (O2), each oxygen atom has a -1 oxidation number which combine to give peroxide its -2 CHARGE. The oxidation number of oxygen in COMPOUNDS is usually -2, but it is -1 in peroxides. The sum of the oxidation numbers of all the atoms in a NEUTRAL COMPOUND is 0. The oxidation number of H is +1 (Rule 1).
