Describe the preparation of 5L of 0.3M acetate buffer, pH 4.47, starting from a 2M solution of acetic acid and a 2.5M solution of KOH. Take Pka as 4.77. How many moles of sodium acetate and acetic acid are required to prepare IL of buffer, pH 5.0, which is 0.1M in total available acetate (dissociated and undissociated)? Acetic acid ha a pka of 4.74.
