How many coulombs of electricity is required to reduce 1 mole of `Cr_2

1.	How many coulombs of electricity is required to reduce 1 mole of `Cr_2O_7^(2-)` in acidic medium?A. 4 x 96500 CB. 6 x 96500 CC. 2 x 96500 CD. 1 x 96500 C
Answer» Correct Answer - B In acidic medium , dichromate ions are reduced according to the equation, `Cr_2O_7^(2-) +14H^+ + 6e^(-) to 2Cr^(3+) + 7H_2O` 1 mole of `Cr_2O_7^(2-)` ion requires 6 moles of electrons or 6 x 96500 C of electricity
