Which sketch best represents the qualitative molecular view of an aqueous solution of nitrous acid? (Water molecules are not shown explicitly.)

Question

Quizplus · Accepted Answer

Sketch B shows the qualitative molecular view of an aqueous solution of nitrous acid, where the nitrous acid molecules partially dissociate into hydronium ions (H3O+) and nitrite ions (NO2-). This is consistent with the chemical equation for the dissociation of nitrous acid in water: HNO2 + H2O ⇌ H3O+ + NO2-. Sketches A, C, and D do not represent the dissociation of nitrous acid in water.
