A buffer solution contains 0.384 M KHCO3 and 0.239 M Na2CO3. If 0.0464 moles of potassium hydroxide are added to 225.0 ml of this buffer, what is the PH of the resulting soulution? (Assune the volume does not change) I saw a few others posted this question on here, but is there a way to do this problem without using the Ka of HCO3? Either way itd be great to see how to do this problem. Thanks!
