Problem 18.58

Chromium plating is applied by electrolysis to objects suspended in a dichromate solution, according to the following (unbalanced) halfreaction: Cr2O22 7 (aq) 1 e2 1 H1(aq) Cr(s) 1 H2O(l) How long (in hours) would it take to apply a chromium plating 1.0 3 1022 mm thick to a car bumper with a surface area of 0.25 m2 in an electrolytic cell carrying a current of 25.0 A? (The density of chromium is 7.19 g/cm3 .)
