Question

The quantity of electricity needed in coulombs to reduce one centimole of dichromate in acidic medium to chromic state is

Answer 1

Answer:

5.79 × 105 Coulombs

Explanation:

there are 6 electrons ,so that n = 6

Use the formula

Required charge = nF

Plug the values in this formula we get

Required charge = 6 × 96487 Coulombs

= 578922 Coulombs

= 5.79 × 105 Coulombs
