WebbSo the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base. Our base is ammonia, NH three, and our concentration in our buffer solution is .24 molars. We're gonna write .24 here. And that's over the concentration of our acid, that's NH four plus, and our concentration is .20. Webb28 juli 2024 · Predict then calculate the pH of a buffer containing 0.1M HF and 0.12M NaF? (Ka = 3.5 x 10-4) 0.1M HF and 0.1M NaF, when 0.02M HCl is added to the solution? Part a is easy, in part b, should I just add the conc of HCl to HF and plug it in the same Henderson hasselbalch equation? b) No, you can't do that.
