Strong, Weak, and non-electrolytes

strong electrolytes

substances that completely dissociate into ions when they dissolve in water

weak electrolytes

solutes that exist in solution mostly in the form of neutral molecules with only a small fraction in the form of ions

nonelectrolytes

solutions made by molecules that dissolve in water, but do not dissociate; do not conduct electricity
