Prepare a buffer by acid-base reactions. Consider how to prepare a buffer solution with pH = 9.41 (using one of the weak acid/conjugate base systems shown here) by combining 1.00 L of a 0.360-M solution of weak acid with 0.359 M potassium hydroxide. Weak Acid Conjugate Base HNO₂ HCIO HCN NO₂™ CIO CN- Ka 4.5 x 10-4 3.5 x 10-8 4.0 x 10-10 pka 3.35 7.46 9.40 How many L of the potassium hydroxide solution would have to be added to the acid solution of your choice?
