The Element Zinc


Zinc is a moderately reactive bluish grey metal that tarnishes in moist air. It also burns in air with a bright bluish green flame giving off fumes of zinc oxide. Zinc is also readily reactive with acids, alkalis and other non-metals. One of its main characteristics is that when it is not completely pure, zinc will react with dilute acids to give off the hydrogen gas.

Industrially zinc is used widely to galvanize steel to prevent corrosion, in conjunction with other metals to form alloys such as brass, nickel silver and typewriter metal. In automobile industry zinc is used in die casting.
