A chemistry student wants to create a buffer solution with a pH of 7.2 using acetic acid and sodium acetate. The student has calculated that they need 0.1 moles of each component to make a 250 mL buffer solution. However, the student accidentally added 0.02 moles of hydrochloric acid to the buffer solution. Calculate the new pH of the buffer solution and explain if the addition of the hydrochloric acid has shifted the equilibrium position of the reaction towards the acid or the base.
