Question

an ionic compound does not conduct electricity in solid state,but when it is issolved in water , it conducts electricity due to the dissociation into ions. why do ions conduct electricity

Answer 1

Ions are positively and negatively charged.Now, the motion of electrons constitutes current. Similarly, the motion of ions in a water constitutes current.The positive ions move towards the negative plate and negative ions move towards the positive plate thus completing the circuit and conducting electricity.
