Question:

A current density of 0.1 A/cm2 is applied to the iron in an iron-zinc corrosion cell. Calculate the weight loss of zinc per hour
(a) If the zinc has a surface area of 10 cm2 and the iron has a surface area of 100 cm2 and
(b) If the zinc has a surface area of 100 cm2 and the iron has a surface area of 10 cm2.
