PLS SAY CHEM Q

S0₂

SO_{2}

HOW PLEASE EXPLAIN

SO2 doesn't need the precense of moisture

Riddle i think it does require water

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

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

O₃ i think

SO₂ needs moisture

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

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