In alkanline medium ClO_(2) oxidises H_(2)O_(2) to O_(2) and itself gets reduced to Cl^(-). How many moles of H_(2)O_(2) are oxidised by 1 mol of ClO_(2)?

Answer»

`1.0`
`1.5`
`2.5`
`3.5`

Solution :`(({:(2ClO_(2)+2OH^(-)to2Cl^(-)+H_(2)O+5[O]),(H_(2)O_(2)+[O]toH_(2)O+O_(2)xx5):})/(5H_(2)O_(2)+2ClO_(2)+2OH^(-)to6H_(2)O+2Cl^(-)+5O_(2)))/`
THUS, ONE mole of `ClO_(2)` oxidises 5/2 or 2.5 moles of `H_(2)O_(2)`
