Acetic acid, HOAc, has a Ka = 1.73x10^-5. You need to prepare a buffer solution with a pH of 5.00 from a solution of 1M acetic acid (HOAc) and 1 M sodium acetate (NaOAc). How many mL of NaOAc should be added to the 30mL of HOAc solution to create the buffer? Using this buffer as an example, provide the reactions that allow the buffer to resist changes in pH upon addition of 1) NaOH and 2) HCl.

an aqueous solution contains 0.361 M acetic acid (HOAc). If you add 83.0mL of 0.278 M potassium hydroxide to 150 mL of this solution, what is the final pH? (Ka of HOAc = 1.8*10-5
The acetic acid/acetate buffer system is a common buffer used in the laboratory.
The acetic acid/acetate buffer system is a common buffer used in the laboratory. Write the equilibrium equation for the acetic acid/acetate buffer system. The formula of acetic acid is CH3CO2H. equilibrium equation: Which way does the equilibrium shift if more H3O+ is added? The equilibrium will not change. The equilibrium will shift to the left. The equilibrium will shift to the right. Which way does the equilibrium shift if more OH- is added? The equilibrium will shift to the right. The equilibrium will shift to the left. The equilibrium will...
