Question

HNO₃ is a strong acid. When an equal molar amount of KOH is added to an HNO₃ solution, an acid-base reaction takes place. Which of the following figures depicts the reaction mixture when the system reaches equilibrium? Note that K⁺ ions have been omitted for clarity.

Diagram A shows H3O+, H2O, and HNO3 molecules before equilibrium.

Accepted Answer

Diagram D shows H3O+, H2O, and HNO3 molecules in another configuration.

Answer

Diagram B illustrates the reaction mixture of H3O+, H2O, and HNO3 at equilibrium.

Answer

Diagram C depicts H3O+, H2O, and HNO3 molecules in a different arrangement.

Answer

Diagram E presents H3O+, H2O, and HNO3 molecules in a varied layout.
