PLS SAY CHEM Q

IS it rite?

Riddle i think it does require water

It is dry bleaching since it bleaches by the process of reduction.

i don't know u maybe correct !

I think O₃......cos it bleaches thro' the production of nascent oxygen by the reaction

O₃------> O₂+[O]

I'M NOT SURE THOUGH

Nishant Bhaiyya help pls

yes strider i agree wid u ...its O3 i think...due to the production of active oxygen ie nascent oxygen

Actually, SO2 is a reducing agent. When it reacts with water, it produces sulfonic acid, H2SO3. The anion of this acid is sulfite and bisulfite. These are added to foods to block the action of oxidation from atmospheric oxygen.

Hint: Look up the Kraft sulfite bleaching process.

and as abhi, strider(ani) and arathi say, ozone is correct

Some one pls tell me which is the correct answer

DRY blaech is for O3 ,Cl and SO2 both needs moisture
