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).

Answer»

Volume of `I^(-)` solution taken is 30mL
Volume of `I^(-)` solution taken is 50mL
Per MOLE `MN^(2+)` formed, 4 MOLES of `H^(+)` are consumed
Per mole `IO_(3)^(-)` formed, 2 moles of `MnO_(4)^(-)` are consumed
