What is the equilibrium chemical equation?

Calculate the pH of a 1.00 L solution that is 0.150 M in Benzoic acid (HC 7 H 5 O 2 ) and 0.050 M in potassium benzoate (KC 7 H 5 O 2 ). The pK a of benzoic acid is 4.20. This is a buffer solution since it contains a weak acid and its conjugate base (a salt of the acid).
