Citric acid (192.13 g/mol) is a triprotic acid with thefollowing chemical formula: H3C6O7H5.
The acid dissociation constants for citric acid are:
Ka1 = 7.1 x 10^-4 M; Ka2 = 1.7 x 10^-5 M; Ka3 = 6.4 x 10^-6M
Describe how you would prepare at least 100.00 mL (you may makemore) of a citrate buffer with a pH of about 4.40. You haveavailable distilled water, volumetric flasks and any sodium saltsyou desire. You must indicate the amount in grams of materialneeded (except for water, you may use volume). Your designed buffermust have a reasonable buffer capacity and no solution you make canhave a concentration greater than 0.500 M.
