Amalgam (chemistry)

Important amalgams Zinc amalgam. Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction). It is the reducing agent in the Jones reductor, used in analytical chemistry.Formerly the zinc plates of dry batteries were amalgamated with a small amount of mercury to prevent deterioration in storage. It is a binary solution (liquid-solid) of mercury and zinc.

Zinc

Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table.In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of

Zinc group element

The estimate for cadmium is only 0.15; commercially, it is always found associated with zinc or zinc–lead ores and is produced only as a by-product of zinc and lead smelting.
