Which of the following is NOT an application of chemical effects of electric current?

The Correct answer is electromagnetism

Explanation:

• Electrolysis: It is an application of the chemical effects of electric current. By passing an electric current through an electrolyte (a conductive liquid, often a solution of salts or other compounds), chemical reactions are induced, including those that cause the electrolyte to decompose.
• Electroplating: This also directly involves the chemical effects of electric current. In electroplating, a metal object is coated with a layer of a different metal. This is achieved by passing an electric current through a solution that contains ions of the coating metal, causing these ions to adhere to the object.
• Electromagnetism: This is NOT considered an application of the chemical effects of electric current. Electromagnetism involves the generation of a magnetic field around a current-carrying conductor, which is a different kind of effect - a physical one, not a chemical one.
• Galvanization: This involves the use of electric current to apply a protective layer of zinc to iron or steel, to prevent rusting. Therefore, it's a type of electroplating and IS a result of the chemical effects of electric current.
