A nonelectrolyte is a compound that, when dissolved in water, does not dissociate into ions. An electrolyte is a compound that dissociates into ions when dissolved in water. A solution containing an electrolyte conducts electricity whereas a solution of a nonelectrolyte does not conduct electricity. A weak electrolyte does not dissociate completely in water, but a strong electrolyte dissociates completely into ions when dissolved in water.

Work Step by Step

A weak electrolyte, when dissolved in water, mostly remains in molecular form and not in ionic form. Strong acids are strong electrolytes. Weak acids are weak electrolytes. Most ionic compounds are strong electrolytes. Molecular compounds tend to be weak electrolytes.
