Consider how best to prepare one liter of a buffer solution with pH = 9.78 using one of the weak acid/conjugate base systems shown here. Weak Acid Conjugate Base Ka 6.4 x 10-5 6.2 x 10-8 4.8 x 10-11 HC₂04 H₂PO4 HCO3 C₂04²- HPO42- CO3²- pka 4.19 7.21 10.32 How many grams of the sodium salt of the weak acid must be combined with how many grams of the sodium salt of its conjugate base, to produce 1.00 L of a buffer that is 1.00 M in the weak base? grams sodium salt of weak acid = grams sodium salt of conjugate base =
