Answer 2

The passage of an electric current through a solution causes chemical effects.

Explanation:

• Chemical effect of electric current was discovered by Luigi Galvani.
• In chemical effect, gas bubbles are formed at the electrodes, metals are deposited and colour change of the solution takes place.
• Depending on the solution and electrodes, the chemical reaction occurs.
• Chemical effects can be used in electroplating, extracting metals from ores, purification of metals, production of compounds.
• The process of depositing a layer of metal on other material by using electricity is known as electroplating.
