Frequently Asked Questions
The chemical effect of electric current refers to the changes that occur in a substance when an electric current passes through it, such as decomposition of the substance, formation of gas bubbles, or deposition of metals.
Electroplating is the process of coating an object with a thin layer of metal using electricity. This is done to prevent rusting, improve appearance, or give a protective coating.
Liquids like saltwater, acids, and alkalis are good conductors of electricity because they contain free ions that carry electric charge.
