9. If you mix 0.05 mol of sodium acetate and 0.06 mol of acetic acid in 1 L of water, what would be the pH of the solution? (pKa of acetic acid is 4.76)- Solution A

a. If you add 0.01 mol of NaOH to solution A, what would be the pH of the solution?

b. If you add 0.01 mol of NaOH to 1 L of water, what would be the pH of the solution?

c. If you add 0.01 mol of HCl acid to solution A, what would be the pH of the solution?

d. If you add 0.01 mol of HCl acid to 1 L of water, what would be the pH of the solution?

e. Based on your calculated pH values, explain why solution A is a better buffer compared to water.

f. Write equation for acetic acid/acetate buffer system (solution A).

g. When you add HCl to the buffer, does it increase or decrease the acetic acid concentration? Does it increase or decrease the acetate concentration? Does it increase or decrease the pH? Do your results follow the Le Chatelier's principle? Explain.

h. When you add OH- to the buffer, does it increase or decrease the acetic acid concentration? Does it increase or decrease the acetate concentration? Does it increase or decrease the pH? Do your results follow the Le Chatelier's principle? Explain.

i. Write equation for carbonic acid/bicarbonate buffer system in blood.

j. Predict whether blood pH increase or decrease in the given conditions:

Adding sodium bicarbonate

Holding your breath

Vigorous exercise
