A 0.46 g sample of As_(2)O_(3) required 25.0 " mL of " KMnO_(4) solution for its titration. The molarity of KMnO_(4) solution is

A solution of H_(2)O_(2) labelled as '20 V' was left open. Due to this some, H_(2)O_(2) decomposed and volume strength of the solution decreased . To determine the new volume strength of the H_(2)O_(2) solution, 10 mL of the solution was taken and it was diluted to 100 mL . 10 mL of this diluted solution was titrated against 25 mL of 0.0245 M KMnO_(4) solution under acidic condition. Calculate the volume strength of the H_(2)O_(2) solution .

Pyrolusite is the main ore of manganese in which it is present as Its Mn content is determined by reducing it under acidic condition to Mn^(2+) with the help of oxalate (C_(2)O_(4)^(2-)) ion which in turn gets oxidized to CO_(2) The analytical determination is carried out by adding a known excess volume of (C_(2)O_(4)^(2-)) solution to a suspension of the pyrolusite and digesting the mixture on a hot water bath until all the MnO_(2) has been reduced. The excess unreacted oxalate solution is then titrated with standardized KMnO_(4) solution. Thereby Mn content of ore can be calculated. KMnO_(4) solution is also standardized under acidic condition against oxalate ion wherein MnO_(4)^(-) ion is reduced to Mn^(2+) and (C_(2)O_(4)^(2-)) ion is oxidized to CO_(2) Q of pyrolusite ore were treated with of pure ferrous ammonium sulphate FeSO_(4).(NH_(4))_(2)SO_(4)6h_(2)O) and dil. H_(2)SO_(4) After the reaction solution was diluted to . of dilute solution required 10 mL of 0.1NK_(2)Cr_(2)O_(7) solution. What is the amount of ferrous ammonium sulphate in 500 mL of solution, which is neutralized by K_(2)Cr_(2)O_(7) solution ?
