Which among the following reactions exhibits the reducing property of ozone?
Options
- APbS _ ( s ) +4 O _ 3( ~g ) PbSO _ 4( ~s ) +4 O _ 2( ~g )
- BBaO _ 2( ~g ) + O _ 3( ~g ) BaO _ ( s ) +2 O _ 2( ~g )
- CNO _ ( g ) + O _ 3( ~g ) NO _ 2( ~g ) + O _ 2( ~g )
- D2 KI _ ( aq ) + H ₂ O _ ( l ) + O _ 3( ~g ) 2 KOH _ ( aq ) + I _ 2( ~g ) + O _ 2( ~g )
Correct answer
B. BaO _ 2( ~g ) + O _ 3( ~g ) BaO _ ( s ) +2 O _ 2( ~g )
Step-by-step solution
Ozone is a reducing agent: Ozone converts peroxides to oxides and is converted to oxygen in exchange. Barium peroxide is reduced to barium oxide by ozone. BaO ₂+ O ₃ BaO +2 O ₂
