Explanation:
Answer : The time it take to plate out will be, 3.69 minutes.
Explanation :
First we have to calculate the moles of Cr.
Molar mass of Cr = 51.9 g/mol
The cathode half-reaction is,
From this we conclude that,
The number of electrons (n) in the reaction are 3.
The quantity of charge required for the reduction of 1 mole of =
The quantity of charge required for the reduction of 0.0423 mole of =
Now we have to calculate the time taken.
We know that,
Thus, the time it take to plate out will be, 3.69 minutes.
