The substance that conducts electricity when dissolved in water has to be identified. Concept introduction: Electrolytes: Ionic compounds dissociate in to two different ions like cation and anion, therefore its conduct the electricity. Ionic compounds are electrolytes, because it conducts an electric current when dissolved in water. Strong electrolyte: A compound that completely dissociates into its ions in aqueous solution. Strong acids and strong base are strong electrolyte because, they ionize completely. Strong electrolytes conduct the electricity. Weak electrolyte: A compound that dissociates partially in an aqueous solution. Aqueous solutions of weak electrolytes conduct less electricity. Weak acids and weak base are weak electrolyte because, they do not ionizing completely. Nonelectrolyte: Nonelectrolytes are not ionizing compound molecular compound. They do not conduct the electricity.

Concept introduction:
Electrolytes:
Ionic compounds dissociate in to two different ions like cation and anion, therefore its conduct the electricity. Ionic compounds are electrolytes, because it conducts an electric current when dissolved in water.
Strong electrolyte:
A compound that completely dissociates into its ions in aqueous solution. Strong acids and strong base are strong electrolyte because, they ionize completely. Strong electrolytes conduct the electricity.
Weak electrolyte:
A compound that dissociates partially in an aqueous solution. Aqueous solutions of weak electrolytes conduct less electricity. Weak acids and weak base are weak electrolyte because, they do not ionizing completely.
Nonelectrolyte:
Nonelectrolytes are not ionizing compound molecular compound. They do not conduct the electricity.
