A biochemistry student wants to make an acidic buffer with pH of 4.20. They will start with 250 mL of a 0.5 M acetic acid (HC2H3O2) solution. Acetic acid has a pka of 4.75. There are two ways to make this buffer. 1.1 The student is given 250 mL of a 0.5 M acetic acid (HC2H;O2) solution. What mass (in g) of sodium acetate (NaC,H;O2: 82.03 g/mol) should they add to make this a solution with pH of 4.20? Round your answer to 3 significant digits. Assume that dissolving the solid will not change the volume of the solution. g of Nac,H;O2 1.2 The lab is currently out of sodium acetate. A friend suggests using sodium hydroxide. How does adding sodium hydroxide to an acetic acid solution make a buffer solution? Explain using a chemical equation. No calculation needed.
