Which of the following describes a solution containing an electrolyte?
The solute particles are so firmly bonded that they do not break apart.
The solute particles permit the passage of electric current.
It is unstable, and all the solute particles will precipitate if the solution is disturbed.
It cannot contain any more solute particles.

The solute particles permit the passage of electric current.

Explanation:

An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. The dissolved electrolyte separates into wo kinds of ions; cations and anions, which disperse uniformly through the solvent. An electrolyte is simply seen as any substance that conducts electricity when dissolved in water. This definition of an electrolyte can further be simplified as a chemical compound that conducts electricity by changing into ions when melted or dissolved into a solution. An example of an electrolyte is molten or aqueous sodium chloride.

Hence in an electrolyte, the solute must allow the passage of electric current since the charge carries are produced when electricity causes the ionic compound to break apart in to its constituent ions. If the solute does not allow electricity to pass through it, its solution can not be an electrolyte.
