Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to impro ...
industry, in processes such as immersion zinc plating and electroplating (electrogalvanization Electrogalvanizing is a process in which a layer of zinc is bonded to steel in order to protect against corrosion. The process involves electroplating, running a current of electricity through a saline/zinc solution with a zinc anode and steel condu ...

Inorganic compound nomenclature
In the naming
Naming is assigning a name to something.
Naming may refer to:
* Naming (parliamentary procedure), a procedure in certain parliamentary bodies
* Naming ceremony, an event at which an infant is named
* Product naming, the discipline of deciding wh ...
of inorganic compounds, "-zincate" is a suffix that indicates that a polyatomic anion contains a central zinc atom. Examples include tetrachlorozincate, ZnCl42−, the tetrahydroxozincate, Zn(OH)42− and tetranitratozincate, Zn(NO3)42−. More recent recommendations ( 2005), that are not widely used, would call the first two ions tetrachloridozincate(2−) and tetrahydroxidozincate(2−) respectively.
