    What is the weight in gram of available O_(2) per litre from a solution of H_(2)O_(2) , 10 mL of which when titrated with N//20 KMnO_(4) solution required 25 mL for the reaction ? 2KMnO_(4)+5H_(2)O_(2)+4H_(2)SO_(4)to 5O_(2)+8H_(2)O+2KHSO_(4)+2MnSO_(4)

    In a reaction excess of H_(2)O_(2) is added to 0.1 mole of acidified KMnO_(4) solution. Then the S.T.P volume of O_(2) liberated is

    H_(2)O_(2) is an unstable liquid . On standing or on heating it decomposes to H_(2)O and O_(2) . H_(2)O_(2) can acts as oxidising agent and reducing agent . The concentration of H_(2)O_(2) is expressed differently with volume strength and the concentration of H_(2)O_(2) at a particular time is measured by titrating it with acidified KMnO_(4) or by titrating liberated I_(2) from acidified KI and H_(2)O_(2) with hypo solution . A sample of H_(2)O_(2) has 3.4 g of H_(2)O_(2) in 100 mL solution . The bottle containing this sample was kept at 25^(0)C for 15 days then 20mL of this sample is treated with excess KI and the liberated iodine requires 50 mL , 0.2 M Na_(2)S_(2)O_(3) solution . Assume the volume of solution remains unchanged . The volume of H_(2)O_(2) sample (after 15 days ) that is required to reduce 40 mL of 0.2 M acidified KMnO_(4) solution is :

    For completely reacting with 400 mL of 1 N acidified KMnO_(4) solution, what volume of a 10 volume sample of H_(2)O_(2) is needed?

    Assertion If 10 mL of a H_(2)O_(2) solution required 8.00 mL of 0.02 M acidified KMnO_(4) solution for complete oxidation, 12.50 mL of same H_(2)O_(2) will oxidise completely to 5.00 mL of 0.10 M Na_(2)C_(2)O_(4) solution. Reason H_(2)O_(2) act as both oxidising as well as reducing agent.
