प्रश्न
A solution of caustic soda (NaOH) in water or when fused, conducts an electric current. what is the similarity in these two cases?
उत्तर
Caustic soda (NaOH) in water or in a fused state conducts electricity due to the dielectric effect of the polar water molecules, which overcomes electrostatic attraction and allows the ions to move freely.
The high temperature needed to melt the solid weakens the bond between the particles in the molten state (fused), releasing the ions.
