In a biochemistry laboratory, you are asked to prepare a buffer solution to be used as a solvent for isolation of an enzyme. On the shelf are the following solutions, all 1.00 M: formic acid (Ka = 1.8 × 10-4), acetic acid (Ka = 1.8 × 10-5), sodium formate (NaHCO2), and sodium acetate (NaCH3CO2). Describe how you would prepare 1.0 L of a pH = 4.65 buffer solution with total molarity of 0.32 M.

1. Why was it important to use "flat" soft drinks for your titrations? Would your calculations of the molarity of citric acid have been too high or low if you hadn't used a "flat" soft drink? 2. Grape juice contains diprotic acid, tartaric acid, which has the molecular formula C4H6O6. If 20.00 mL of grape juice required 36.00 mL of 0.0500 M NaOH for the titration to a pink endpoint, what is the molarity of tartaric acid on the grape juice? 3. Diet Big Red soda contains citric acid, as shown in the ingredient list below, Carbonated Water, Citric Acid, Natural and Artificial Flavors, Sucralose, Sodium Benzoate, Caffeine, Malic Acid, Red 40, Acesulfame Potassium, Phosphoric Acid, and Acacia Gum What are two obvious reasons that we did not try to determine the citric acid content in a "flat" sample of Diet Big Red soda?
