Explain why, ionic compounds conduct electricity in solution whereas covalent compounds do not conduct electricity.

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 3. Metal and Non-Metal

Answer :

Ionic compounds are made of electrically charged ions so these electrically charged ions are responsible for conduction of electricity but on the other hand covalent compounds are made up of electrically neutral molecules so they do not conduct electricity.
