3. Potassium sorbate, KC6H7O2 (molar mass=150. g/mol), is commonly added to diet soft drinks as a preservative. A stock solution of potassium sorbate (aq) of known concentration must be prepared. A student titrates 56.6 ml of stock solution with 1.50 M of HCl (aq). a) Write out a net ionic equation for the reaction between KC6H7O2 (aq) and HCl(aq). b) What is the concentration of the stock solution of KC6H7O2(aq) if it takes 65.6 ml of 1.50 M HCl (aq) to reach the equivalence point?
