At 25oC, a 1-L buffer solution is prepared by mixing acetic acid and sodium acetate. A) If the solution is to be buffered at pH = 5, what should be the molar ratio of sodium acetate to acetic acid? B) If the buffer is found to be 1.50M in acetic acid and 1.75M in sodium acetate, what will be the pH of the solution? C) If 0.05 mol of NaOH was added to the solution in B, what will be the pH of the solution? D) If the pH of the solution in B is 4.55, how many moles of HCl was added to the solution?
