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

20 mL of a solution containing 0.2g of impure sample of H_(2)O_(2) reacts with 0.316 g of KMnO_(4) (acidic). Calculate: (a) Purity of H_(2)O_(2) , (b) Volume of dry O_(2) evolved at 27^(@)C and 750 mm P .

A solution of 0.4 g sample of H_(2)O_(2) reacted with 0.632 g of KMnO_(4) in presence of sulphuric acid. The percentage purity of the sample of H_(2)O_(2) is :

The amount of H_(2)O_(2) required for decolourising 1 mol of KMnO_(4) it an acid solution is-

0.2 g if a sample of H_2 O_2 required 10 ml of 1 N KMnO_4 for titration in acidic medium. The percentage purity of H_2 O_2 sample is:

0.2 g if a sample of H_2 O_2 required 10 ml of 1 N KMnO_4 for titration in acidic medium. The percentage purity of H_2 O_2 sample is:
