Question: design a buffer that has a ph of 345 using...

Question details

Design a buffer that has a pH of 3.45 using one of the weak acid conjugate b systems shown below. Weak Acid Conjugate Base Ka pKa 6.4 x 103 4.19 HC zou C204 HPO4 2- 6.2 x 10 721 4.8 x 10 10.3 CO3 How many grams of the potassiuni salt of the weak acid must be combined with how many grams of the potassiun salt of its conjugate base, to produce 1.00 L of a buffer that is 1,00 M in the weak base? grams potassium salt ofweak acid grams potassium salt of conjugate base
