Chemical Effects of Electric Current Electroplating

When electric current is passed through the copper sulphate solution, copper sulphate dissociates into copper and sulphate. The free copper gets drawn to the electrode connected to the negative terminal of the battery and gets deposited on it. Electroplating Chemical Effects of Electric Current

From the other electrode, a copper plate, an equal amount of copper gets dissolved in the solution. Thus, the loss of copper from the solution is restored and the process keeps going. This means that copper gets transferred from one electrode to the other. Electroplating Chemical Effects of Electric Current

The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating. Electroplating is widely used in industry for coating metal objects with a thin layer of a different metal.For example, chromium plating is done on many objects such as car parts, bath taps, wheel rims and many others. Chemical Effects of Electric Current Electroplating

Tin cans, used for storing food, are made by electroplating tin onto iron. Tin is less reactive than iron. Thus, food does not come into contact with iron and is protected from getting spoilt. Chemical Effects of Electric Current Electroplating
