Properties: Zinc is bluish shiny silver metal, hardness 2.5, pure zinc malleable, containing a small amount of impurities are brittle. Good heat transfer, electrical conductivity, chemical properties of more reactive. Room temperature in the air more stable. Humid air generated in the layer of gray basic zinc carbonate can be used as protective film. Zinc has blue-green flame when burned. Reaction with water vapor at high temperature release of hydrogen. When heated with halogen, sulfur and other reactions. Easily with acid reaction, but the slow response of high purity zinc, if a small amount of copper sulfate solution, or with copper, nickel, platinum and other metal contact, the reaction accelerated. Soluble in alkali solution to produce zinc salts
