4.The stockroom contains 1.0 M NaAc (Sodium Acetate), 1.0 M HAc (acetic Acid), distilled water and strong acids and bases. You need to create a buffer solution that has a pH of 4.75 such that when 1.00 mL of 10.0 M HCl is added to 100.00 mL of your buffer, the resulting pH is 3.75 (+/- 0.1). What concentrations of HAc and NaAc do you need to create the buffer solution? Show your calculations and also write out steps on how you "virtually" performed the titration.
