A 20 ml solution containing 0.2 g impureH_(2)O_(2)reacts completely with 0.316 g ofKMnO_(4)in acidic medium. What would be volume strength ofH_(2)O_(2)solution? [Given: Molar mass ofH_(2)O_(2)=34 & KMnO_(4)= 158 g/mol]

Answer»


Solution :Meq of `H_(2)O_(2)=` Meq of `KMnO_(4)`
`(W xx1000)/(17)=(0.316)/(158//5)xx1000`
`W_(H_(2)O_(2))=0.18 gm`.
Normality of `H_(2)O_(2)=(w)/(E )xx(1000)/("Volume (in ML)")=(0.17)/(17)xx(1000)/(20)=0.5`
Volume strength `= N xx5.6=0.5xx5.6=2.8`
