15,000 ml of pH 5.00 acetic acid-sodium acetate buffer solution is prepared as follows 10,000 ml sodium hydroxide solution and 10,000 ml acetic acid solution, each of approximately 0.5 N concentration, are made. The actual concentrations of acetic acid solution and sodium hydroxide solution are determined by titration and are found to be 0.500 N and 0.426 N respectively. Using these values, a 15,000 ml ph 5.00 acetic acid-sodium acetate buffer is prepared by adding 6420 ml of sodium acetate to 8580 ml of acetic acid.
