A chemistry student wants to determine the effect of adding a buffer solution on the equilibrium position of an acetic acid-sodium acetate reaction. The initial concentrations of acetic acid and sodium acetate are both 0.1 M and the pH of the solution is 4. Calculate the new concentrations of acetic acid, acetate ion, and hydrogen ion after adding a buffer solution containing 0.2 M acetic acid and 0.2 M sodium acetate. What is the new pH of the solution?
