A buffer solution is prepared by adding 32.8 grams of sodium acetate, NaC2H3O2 to 1.00 L of 0.500 M acetic acid, CH3CO2H. Ka = 1.8 x 10-5 for acetic acid.
a. What is the pH of the buffered solution?
b. What is the pH of the buffered solution if 0.320 grams of NaOH is added?
c. What is the pH if 0.010 mole of HCl gas is bubbled into the original buffered solution?
