lectricity

Answer 1

Activity

Aim: To show that ionic compounds conduct electricity in water

Materials Required: Beaker, water, common salt, connecting wires, cell/battery, key, bulb.

Procedure:

1. Half fill the beaker with distilled water and add 2 spoons of NaCl to it.
2. Dip the bare end of two wires in it.
3. Connect the wires to a bulb and to a source (cell/battery).
4. On switching the circuit on, the bulb will glow.

Observations and Conclusion:

This shows that ionic compounds conduct electricity in water. This is because in water, they get ionized to form their respective ions, which carry current.
