A buffer contains 5.00 M acetic acid and 5.00 M acetate anion. Gaseous HCl (0.010 mole) is added to 1.00 L of this buffer solution (the total volume does not change). For this buffer solution, the initial pH is_______and the final pH after the addition of the HCl gas is_______ . For acetic acid, Ka = 1.8 x 10-5.
Help me fill in the blanks please? please explain.
Use the Henderson-Hasselbalch equation for part 1. For th second part, HCl will cause an increase in acetic acid concn and a decrease in acetate concn. Post your work if you get stuck.
