Some metals, similar to aluminum and sodium, have no commercially practical reducing agent, and are extracted using electrolysis as a substitute. The Earth’s crust is made of roughly 25% of metals by weight, of which 80% are gentle metals similar to sodium, magnesium, and aluminum.

Despite the general shortage of some heavier metals corresponding to copper, they’ll turn into concentrated in economically extractable quantities because of mountain constructing, erosion, or different geological processes. Painting, anodizing or plating metals are good ways to stop their corrosion. However, a more reactive metal in the electrochemical sequence should be chosen for coating, especially when chipping of the coating is anticipated. Water and the two metals kind an electrochemical cell, and if the coating is less reactive than the underlying metal, the coating really promotes corrosion. The atoms of metallic substances are sometimes arranged in one of three frequent … Read More
