Types of Electrolytes

An electrolyte is a substance that will conduct electricity when dissolved in water. When electrolytes dissolve in water, they disassociate into positive and negative ions. These charged particles are able to facillitate the conduction of electricity through the solution.

  • strong electrolyte is a substance that completely disassociates into ions when dissolved in water.
  • weak electrolyte is a substance that only partially disassociates into ions when dissolved in water. This means that some of the substance remains in its original form and does not disassociate into ions. 
  • nonelectrolyte is a substance that does not disassociate into ions when dissolved in water. 

Potassium chloride (KCl) is a strong electrolyte because it completely diassociates into positively charged potassium ions and negatively charged chloride ions when dissolved in water.
