accodong to the report. benzoic acid solution -weight out 0.61 (5.0 mmoles) of benzoic acid and place the acids in 250-ml flask with 150ml of water add and heated. after rinsing with water to transfer acid. when the solution cool adjust the volume to 250-ml to give 0.020M solution of benzoic acid.
Naoh solution-with one pellets of naoh dissolve in 100 ml of water and rinsed. alternately, use a stock solution of 0.02 Naoh. place a 10.0ml sample of the 0.02M benzoic acid in small flask and add one drop of phenolphthalein solution. titrate to a pink end point. repeat with a 10.0ml sample, average the buret readings and calculate the molarity of Naoh. note -the first titration was 6ml and the second was 6ml.
