peroxide are those releases H₂O₂ when reacts with dilute acids for example sodium peroxide reacts with dil. H₂SO₄ to form hydrogen peroxide gas.remember lithium cannot form peroxide while sodium and potasium can form.these contain O-O bond with single bond.super oxide are those when reacts with dilute acid form both H₂O₂and O₂.for example KO₂.these are paramagnetic and coloured due to odd electron system .KO₂ is yellow in colour and use as air purifier because it absorb CO₂ and releases oxygen gas.Rb and Cs only form super oxide with general formula MO₂.KO₂ also used by swimmers in submarine.
