Explanation:
Aim: To prove that ionic compounds are good conductors of electric conductors in their aqueous solutions
Apparatus required:
Beaker, two electrodes, connecting wire, battery, water and sodium chloride
Procedure:
1. Make a circuit as shown in Figure and insert the electrodes into a solution of salt solution(sodium chloride + water).
observation:
The conduction of electricity through a solution involves the movement of charged particles.
A solution of an ionic compound in water contains ions, which move to the opposite electrodes when electricity is passed through the solution. Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.
But ionic compounds conduct electricity in the molten state.
This is possible in the molten state since the electrostatic forces of attraction between the oppositely charged ions are overcome due to the heat.
Thus, the ions move freely and conduct electricity.
NaCl(aq) ------> Na ⁺ ₍aq₎ + Cl⁻₍aq₎
Result: Hence we proved that ionic compounds are good conductors of electric conductors in their aqueous solutions
