The odor of spoiled butter is due in part to butanoic acid (HC4H7O2) which results from the breakdown of the fat in butter. A 0.100M solution of butanoic acid is 1.23% ionized. Write the chemical equation for the ionization of this acid in water. Write the Ka expression for this acid. What is the equilibrium concentration of each product and the reactant?
