Electrolytes which do not furnish ions
Electrolytes: These are the substances that get dissociate into ions in solution and can conduct electricity.
For example HCl (Hydrogen chloride), NaOH (Sodium hydroxide)
Non- Electrolytes: These are the substances that don't get dissociate into ions in solution and can not conducts electricity.
That means they do not furnish ions in solution
For example Sugar, Alcohol (CH3COOH)
Final answer: Electrolytes which do not furnish ions are Non-Electrolytes
