How much charge is required, when 1 mole of `Cr_(2)O_(7)^(2-)` reduce to form I mole of `Cr ^(3+)` ?

A

6F

B

3F

C

1F

D

2F

Text Solution

Verified by Experts

The correct Answer is:
B
Total of 6 electrons are required to form 2 moles of `Cr ^(3+)` therefore to form 1 mole of `Cr^(3+)3F` of charge is required.
