Calculate the volume of 10 volume H_(2)O solution that will react with 200 mLof 2N KMnO_(4)in acidic medium.

Answer»

Solution :Normality of 10 VOLUME `H_(2)O_(2)=("Volume strength")/(5.6)=(10)/(5.6) N`
APPLYING normality equation, `N_(1)V_(1)(H_(2)O_(2))=N_(2)V_(2)(KMnO_(4)`
`(10)/(5.6)xxV_(1)=2xx200` or `V_(1)=(2xx200xx5.6)/(10)=224` mL.
