Hi, I really don't get how to calculate the pH of a buffer solution...I mean I know that the pH of a solution is the negative log of the H3O+ concentration but I don't know how to get to that part...here's the problem...and I would appreciate if someone could actually explain it to me rather than just posting the answer. Thanks so much in advance!
Q:// In a beaker mix 20 mL of 0.1 M Acetic Acid and 25 mL of 0.1 M Sodium Acetate. Calculate the pH of this solution.
Q2:// Also, then add 5 mL of 0.1 M NaOH to this buffer and re-calculate the pH.
I believe it would be pH=-log[H3O+]
The Attempt at a Solution
I don't have much of an idea....help please :)
