Question

Explain with the help of an experiment that conduction occurs in liquid

Answer 1

Answer:

Apparatus Required For Conductivity of Water Experiment :

Drinking Glass – 1

Metal clamps – 4

Pieces of electrical wire – 3

LED bulb – 1 (you can get it from any fancy LED light, i.e. Christmas lights)

Small battery – 1 (you can find it in toys and many general household items)

Distilled water – 1 glass

Salt – 2 tea spoon

How To Setup Circuit for Conductivity of Water Experiment :

Conductivity of Water - Circuit Diagram

1. First of all attach 2 metal clamps to both the ends of one wire.

 

2. Then attach one clamp to one end of 2nd wire and attach one clamp to one end of 3rd wire. Leave one end of both the wires free.

3. Join LED bulb with free ends of 2nd and 3rd wire.

4. Take 1st wire which have clamps at both the ends and fix it’s one clamp with the glass rim and fix another clamp to one terminal of battery.

5. Now take another wire which is attached with LED bulb and fix it’s one clamp on glass rim and fix another clamp to the second terminal of battery.

6. Setup of circuit for the experiment is complete.

 

Steps For Conductivity of Water Experiment :

Experiment 1 :-

1. Fill distilled water in glass up to the rim so that, the clamps get half immersed in water.

2. You will notice that the bulb doesn’t glow.

Result of Experiment 1 :-

It means, the distilled water is bad conductor of electricity.

 

Experiment 2 :-

1. Now the time for magic. Add 2 teaspoon salt in water and mix properly.

2. See the bulb glows instantly as you dissolved the salt in water.

Result of Experiment 2 :-

It means brine solution is good conductor of electricity.
