100 mL of H_(2)O_(2) is oxidized by 100 mL of 1M KMnO_(4) in acidic medium (MnO_(4)^(-) reduced to Mn^(+2) ) 100 mL of same H_(2)O_(2) is oxidized by v mL of 1M KMnO_(4) in basic medium (MnO_(4)^(-)reduced to MnO_(2)). Findthe value of v:

Answer»

500
100
`100//3`
`500//3`

Solution :In acidic medium
Eqts of `H_(2)O_(2)` = Eqts of `KMnO_(4)`
`(100)/(1000)xxMxx2=(100)/(1000)xx1xx5impliesM=2.5`
In basic medium
Eq. of `H_(2)O_(2)` = Eqts of `KMnO_(4)`
`(100)/(1000)xx2.5xx2=(V)/(1000)xx1xx3impliesV=(500)/(3)`
