Potassium sorbate, KC6H7O2 is commonly added to diet soft drinks as a preservative. A stock solution of KC6H7O2 (aq) of known concentration must be prepared. A student titrates 45.00 mL of the stock solution with 1.25 M HCl (aq) using both an indicator and a pH meter. The value of Ka for sorbic acid, HC6H7O2 is 1.7x10-5.

The net ionic equation for the reaction between  KC₆H₇O₂ and HCl is:

C₆H₇O₂⁻(aq) + H⁺(aq) ⇒ HC₆H₇O₂(aq)

What is a net ionic equation?

The net ionic equation is a chemical equation for a reaction that lists only those species participating in the reaction.

  • Step 1: Write the molecular equation between KC₆H₇O₂ and HCl.

KC₆H₇O₂(aq) + HCl(aq) ⇒ HC₆H₇O₂(aq) + KCl(aq)

  • Step 2: Write the complete ionic equation.

HC₆H₇O₂ is a weak acid so we will write it in the molecular form.

K⁺(aq) + C₆H₇O₂⁻(aq) + H⁺(aq) + Cl⁻(aq) ⇒ HC₆H₇O₂(aq) + K⁺(aq) + Cl⁻(aq)

  • Step 3: Write the net ionic equation.

We will not include spectator ions.

C₆H₇O₂⁻(aq) + H⁺(aq) ⇒ HC₆H₇O₂(aq)

The net ionic equation for the reaction between  KC₆H₇O₂ and HCl is:

C₆H₇O₂⁻(aq) + H⁺(aq) ⇒ HC₆H₇O₂(aq)
