Question: 4
A sheet of copper is exposed to oxygen at 1000°C. After 100 h, 0.245 g of copper are lost per
cm' of surface area; after 250 h, 0.385 g/ cm² are lost; and after 500 h, 0.560 g/ em are lost.
i. Determine whether oxidation is parabolic, linear, or logarithmic
ii. Calculate the time required for a 0.76-cm sheet of copper to be completely oxidized. The
sheet of copper is oxidized from both sides.
In preventing corrosion of iron, a stronger reducing agent called sacrificial anode such as zinc is used to coat iron.
