20 ml of H_(2)O_(2) after acidification with dil H_(2)SO_(4), required 30 ml of N/2 KMnO_(4) for complete oxidation. Calculate the % of H_(2)O_(2) in gr/lit.

20 ml of H_(2)O_(2) after acidification with dil H_(2)SO_(4), required

1.	20 ml of H_(2)O_(2) after acidification with dil H_(2)SO_(4), required 30 ml of N/2 KMnO_(4) for complete oxidation. Calculate the % of H_(2)O_(2) in gr/lit.
Answer» 10.75 g/lit 11.75 g/lit 12.75 g/lit 13.75 g/lit Solution :MEQ. of `O_(2)="Meq. of "H_(2)O_(2)="Meq. of "KMnO_(4)` `(W times 1000)/(34//2)=1/2 times 30` `W=1/2 times (300 times 17)/1000=0.255 gr//20ml` `N_(H_(2)O_(2))=0.255/17 times 1000/20=0.75` STRENGTH `=0.75 times 17=12.75` gr/lit
