Question
Chromium plating is applied by electrolysis to objects suspended
in a dichromate solution, according to this half-reaction:
Cr20,2 + H* + e" -> Cr(s) + H2O (unbalanced)
How long (in hours) would it take to apply a chromium plating
0.0010 cm thick to a car bumper with a surface are of 2500 cm2
in an electrolytic cell carrying a current of 10.0 A at 100%
efficiency? The density of chromium is 7.19 g/cm3. AW of Cr =
52.
