Question

In what sense is a strong electrolyte “strong”? What property of the substance makes it a strong electrolyte?

Short answer

Electrolytes can dissociate into ions to produce electricity. A strong electrolyte is an electrolyte that can dissociate into ions completely.

Step-by-step solution

Concentration of the solution

A solution can be formed from the dissolution of a solute in a solvent. A solute decides the nature of a solution.

Colligative properties can be defined as the property of a molecule, which depends upon the force of attraction between the molecules. The properties depend upon the number of moles of solute in a solvent. As the dilution of a solution increases, the colligative properties of a molecule change.

Electrolytes \ do not produce electricity when in the solid form whereas when an electrolyte dissociates into ions, it starts producing electricity.

Expression to calculate the concentration

The property that describes a strong electrolyte is its “concentration.” A strong electrolyte can be defined as an electrolyte that can dissociate into ions completely and produces electricity. On a dilution, the ions of a strong electrolyte increases but a dissociation of the ions increases up to a certain extent after which a solvent starts to increase and form lesser ions. After a certain point, the electricity production decreases as, on dilution, the ions of the solution also decreases and the solution becomes “dilute.”
