3. A buffer solution is created with the following components: 0.067 M HC,H;O, (acetic acid) 0.075 M NaC,H,O, (sodium acetate) What is the pH of this solution if the K, of acetic acid at this temperature is 1.9 x 10$? a. b. Does this solution provide a better buffer against the addition of strong acid or strong base? Justify your choice. Suppose the concentrations of both acetic acid and sodium acetate are doubled in the container. What happens to the pH of mixture? What happens to the buffering capacity? с.
