(a) Corrosion: Process by which the layers of undesirable compounds are formed on the surface of a metal on its exposure to atmospheric conditions are called corrosion. (b) Electrochemical …
According to electrochemical theory of rusting the impure iron surface behaves like small electrochemical cell in presence of water containing dissolves oxygen or carbon dioxide . In …
When some metals are exposed to moisture, acids etc., they tarnish due to the formation of respective metal oxide on their surface. This process is called corrosion. Corrosion can be …
When zinc coating is applied over iron, it undergoes sacrificial anode, an electrochemical process that acts as a physical barrier and protects the iron from corrosion. But tin has susceptibility to …
When copper is exposed to moist air for a long time then a layer deposits on its surface due to corrosion. The colour of this layer is:
What is corrosion? Corrosion is a process where the metal corrodes. Corrosion is a natural process and in the presence of a moist atmosphere, chemically active metals get corroded. …
