Question

With the help of an activity explain chemical effect of electric current.​

Answer 1

Answer:

Chemical effect of the electric current: The passage of an electric current through a conducting solution causes chemical reaction. That may cause formation of bubbles of a gas on the electrodes, deposites of metal on electrodes, changes of colour of solutions etc.

Explanation:

When an electric current is passed through water, then water dissociates into hydrogen and oxygen. This is an example of the chemical effect of electric current.

Answer 2

Answer:

do experiment with below products

Explanation:

Material under test Good/Bad Conductor

Lemon Juice              Good Conductor

Vinegar             Poor Conductor

Honey                      Poor Conductor

Mercury                      Good Conductor

Soda Compounds                Good Conductor

1. experiment to Demonstrate the Conduction of Electricity in Liquids
2. Construct a circuit with a cell, connecting wires and an LED.
3. Insert the free ends of the wire into a beaker of water without touching each other.
4. If the LED glows, then it is an indication that the liquid is a conductor of electricity and if it doesn’t glow then it is an indicates that the liquid doesn’t conduct electricity.
5. The liquid is a good conductor of electricity if the brightness of the LED is high.
6. Likewise, if the brightness of the LED bulb is low, then the liquid is a bad conductor of electricity.
