Magnesium corrosion products form what appearance?

Explanation:
Magnesium corrosion products are white because the oxide or hydroxide that forms on magnesium—such as magnesium oxide (MgO) or magnesium hydroxide (Mg(OH)2)—is white. This is distinct from other metals: iron oxides form reddish-brown rust or black oxides, copper develops a green patina, and red oxide is characteristic of iron rust. So seeing a white, chalky or powdery film on magnesium surfaces is the telltale appearance of its corrosion products.
