![]() ![]() The chemical changes which take place in conducting liquids on passing electric current through them are called chemical effects of electric current. The liquids which conduct electricity are called conducting liquids. (2) When electricity is passed through a solid, then no chemical change take place but when electricity is passed through a liquid, then a chemical change take place.įor example: When electricity is passed through a copper wire, no chemical change take place in it but when electricity is passed through acidified water, then a chemical change take place in which water is decomposed into hydrogen and oxygen gas. In solid like copper metal, electricity is carried by electrons but in a liquid like copper sulphate solution, electricity is carried by copper ions and sulphate ion. ![]() (1) In solids, electricity is carried by electrons but in liquid, electricity is carried by ions (positively charged and negatively charged ions). There are differences in the conduction of electricity by solids and liquids. A solution of sodium hydroxide, potassium hydroxide or base in water conduct electricity.Ĭopper sulphate, common salt also conduct electricity. Vinegar contains acetic acid and lemon juice contain citric acid also conduct electricity. The liquid that conduct electricity are solutions of acid bases and salts in water.įor example : Solution of sulphuric acid, hydrochloric acid in water conduct electricity. The material such as rubber, plastic, wood do not allow electric current to pass through them so they are poor conductors of electricity. The metal such as copper and aluminium allow electricity to pass through them easily, so they are good conductors of electricity. The material which do not allow electric current to pass through them easily are called poor conductor of electricity. The materials which allows electric current to pass through them easily are called good conductors of electricity.
