`H_(2)O_(2)` reduces `MnO_(4)^(-)` ion to

S_(2)O_(3)^(2-) + MnO_(4)^(-) + H_(2)O rarr MnO_(2) + S_(2)O_(4)^(2-) + OH^(-) . What are the coefficients of S_(2)O_(3)^(2-) and MnO_(4)^(-) in the balance equation ?

How many faraday of electricity is required to reduce 1 mole of MnO_(4)^(-) ions to Mn^(2+) ions?

Explain property of H_(2)O_(2)"with"MnO_(4)^(-) in acidic medium.

100 mL of H_(2)O_(2) is oxidized by 100 mL of 1M KMnO_(4) in acidic medium ( MnO_(4)^(-) reduced to Mn^(+2) ) 100 mL of same H_(2)O_(2) is oxidized by v mL of 1M KMnO_(4) in basic medium ( MnO_(4)^(-) reduced to MnO_(2) ). Find the value of v:
