How do you make sodium phosphate buffer pH 7?
All Answers (9) 39 parts monobasic and 61 parts dibasic sodium phosphate solutions (by volume, with both solutions at 50 mM) at room temperature will give a pH 7 solution. Dissolve 0.2651 g of monosodium phosphate and 0.8253 g of disodium phosphate in 100 ml of water to make 50mM phosphate buffer of pH 7.
