Describe how one would prepare in the laboratory 1.00 liter of a 50 millimolar sodium phosphate buffer solution having a ph of 7.0. The pKa values of phosphoric acid, H3PO4, are 2.14, 6.86, and 12.4. Assume reagent grade 80% (w/w) phosphoric acid solution and a standardized 0.100 M solution of NaOH available and needed glassware.
