Barium permangnate solution (20mL, 0.1 M) is mixed with 0.1 N `I^(-)` giving precipitate fo `IO_(3)^(-)` and `MnO_(2)` . Resulting solution is filtered and titrated against `Mo^(3+)`, giving `MoO_(2)^(2+)` and `Mn^(2+)`. Which required 0.5 M, 10mL acidified `Mo^(3+)` .Select the correct option (s).

Options

A. Volume of `I^(-)` solution taken is 30mL
B. Volume of `I^(-)` solution taken is 50mL
C. Per mole `Mn^(2+)` formed, 4 moles of `H^(+)` are consumed
D. Per mole `IO_(3)^(-)` formed, 2 moles of `MnO_(4)^(-)` are consumed
