An acetic acid/ sodium acetate buffer solution was prepared using the following components:

3.46 g of NaC₂H₃O₂â3H₂O (FW. 136 g/mol)

9.0 mL of 3.0 M HC₂H₃O₂

55.0 mL of water

-What is the total volume of the solution?

-Calculate the concentration of the [C₂H₃O₂^-] in this solution.

-Calculate the concentration of the [HC₂H₃O₂] in this solution.

-Calculate the pH of this buffer solution. The K_a for acetic acid is 1.8x10^-5.

-If you take half of this solution and add 2 mL of 1.00 M HCl to it, then what is the pH of this new solution?

-If you take half of this solution and add 2 mL of 1.00 M NaOH to it, then what is the pH of this new solution?
