Generally, common buffers have concentrations of the acid and base components that are between 0.1 M and 1.0 M. Because the acid is less concentrated, we will set its concentration to 0.100 M. What mass of the acid is required to form 1.00 L of 0.100 M solution? Target pH = 7.71 Acid/Base pair: NaH2PO4/Na2HPO4 pKa = 7.21 [Na2HPO4] > [NaH2PO4] g NaH2PO4

solutions to observe that buffers resist pH changes. Burette readings should be made to the nearest 0.1 mL (or 0.05 mL if possible), A. Preparation of Acetic Acid-Acetate Buffer Solution An acetate buffer contains the acid-base pair, acetic acid and the acetate ion (typically added as sodium acetate). For acetic acid, pK, = -log (1.8 x 10-)...

We dissolve 3.44 g of an unknown acid, HA, in enough water to produce 25.0 mL of solution. We titrate this solution with a 0.250 M solution of NaOH. It takes 18.3 mL of the NaOH solution to reach the equivalence point. The pH at the equivalence point is 12.00. (a) (3 points) What is the molar mass of HA? (b) (3 points) What is the pK, value of HA(aq)? (c) (3 points)...
