A student wishes to prepare a buffer solution by adding 0.20 moles of acetic acid (Ka = 1.8 x 10^-5) and 0.20 moles of sodium acetate in 1 liter of solution. The student adds 0.05 moles of hydrochloric acid (HCl) to the solution. Calculate the effect of adding the buffer on the equilibrium position of the acid-base reaction and determine the new pH of the solution.
