Question

Classify the solute represented in each of the following equations as strong, weak, or nonelectrolyte.

Drag the appropriate items to their respective bins.

O HClO(aq)⇌ H₂OH+(aq)+ClO−(aq)HClO(aq)⇌ H₂OH+(aq)+ClO−(aq)
O CH₄O(l)⟶ H₂OCH₄O(aq)CH₄O(l)⟶ H₂OCH₄O(aq)
O AlCl₃(s)⟶H₂OAl₃+(aq)+3Cl−(aq)AlCl₃(s)⟶H₂OAl³⁺(aq)+3Cl⁻(aq)
O Strong electrolyte
O Weak electrolyte
O Nonelectrolyte

Answer 1

HClO(aq) is a weak electrolyte as it partially dissociates, CH₄O(aq) is a nonelectrolyte as it does not dissociate into ions, and AlCl₃(s) is a strong electrolyte since it dissociates completely in water.

Step-by-step explanation:

The classification of solutes as strong electrolytes, weak electrolytes, or nonelectrolytes depends on the extent to which they dissociate into ions in solution. A strong electrolyte dissociates completely into ions, a weak electrolyte partially dissociates, and a nonelectrolyte does not dissociate into ions at all.

HClO(aq) is an example of a weak acid, which makes it a weak electrolyte because it only partially dissociates into ions. CH₄O(aq), or methanol, is a compound that dissolves into individual neutral molecules without dissociation, classifying it as a nonelectrolyte. AlCl₃, on the other hand, is an ionic compound that dissociates completely in water, making it a strong electrolyte.
