Show an activity in which liquid conduct electricity
Answers
Solutions of most acids, bases and salts dissolved in water are good conductors of electricity. Electrical conductivity of liquids can be tested by a simple activity of taking a liquid, like lemon juice, in a container, inserting electrodes in it, connecting the two electrodes to the terminals of a battery with a bulb (LED) between them. The bulb glows, indicating that lemon juice is a conductor of electricity. Several liquids can be checked for electrical conductivity in the same way.
We find that liquids like lemon juice, liquid soap, rain water, salt solution, etc. conduct electricity, whereas liquids like distilled water, oil, alcohol, etc. do not conduct electricity. When electricity is passed through a conducting solution, the molecules of the solution dissociate into ions. Ions are atoms or group of atoms with a positive or a negative charge. These ions cause electrical conduction through the liquid. A liquid That conducts electricity due to the presence of ions is called an electrolyte.
The process of decomposition of a chemical compound in a solution when an electric current passes through it is called electrolysis. This process is due to the chemical effect of electric current
Answer:
Aim:- to test various liquids for their electrical conductivity.
Materials:- cell , bulb , wire , switch , and a beaker with water solution.
Procedure:- adjust the tester using two cell, switch, wire and bulb .
NOW, take normal water in small beaker or glass bowl and dip the end of a tester in it and watch the bulb glows this shows normal water is a good conductor of electricity you will notice the bulb glow faintly. when bulb replaced by a LED ( Light Emitting Diode ) LED glows when it has weak electric current flows.
Observation:- use other liquid or what does such as lemon juice, soda water, salt solution, Honey, kerosene oil, and distilled water in place of normal water to test other conductivity.
