In an electrochemicalcell, dichromate ions in aqueous acidic medium are reduced to Cr ³⁺ . The current (in amperes) that flows through the cell for 48.25 minutes to produce 1 mole of Cr ³⁺ is _____ . Use: 1 Faraday =96500 C mol ⁻¹

Step-by-step solution

For reduction of dichromate, balanced reaction is : Cr ₂ O ₇⁻²( aq )+6 e ⁻+14 H ⁺( aq ) 2 Cr ³⁺( aq )+7 H ₂ O ( l ) 3 Mole 1 Mole Number of Farads required =3 ~mol Let current = I amperes aligned & I 48.25 60 96500 =3 & I=100 ~A aligned
