A chemistry student wants to see the effect of adding a specific buffer on the equilibrium position of a 0.1 M acetic acid (CH3COOH) and 0.1 M sodium acetate (CH3COONa) solution. If the initial pH of the solution is 4.7, what is the pH of the solution after adding the buffer? (Ka of acetic acid is 1.8 x 10^-5).
