10 uses of chemical effect of electric current
Answers
Answer:
What are the uses of chemical effects of electric current?
Some liquids are good conductors of electricity and some are poor conductors. Most liquids that conduct electricity are solutions of acids, bases and salts. The passage of an electric current through a conducting liquid causes chemical reactions. The resulting effects are called chemical effects of currents.
Answer:
Construct a circuit using two cells, an LED and connecting wires.
Immerse the two free ends of the wires into a beaker containing water or any liquid without touching each other, but also keep in mind that they must not be separated by a large distance.
If the LED glows, the liquid conducts electricity and in case the LED does not glow, we can say the liquid does not conduct electricity.
If the brightness of the LED glow is high, then those liquids are good conductors
In case the brightness of the LED is low, it indicates that less current is going through those liquids and they are poor conductors of electricity.
If the LED does not glow, it denotes that such liquids are insulators.
