WebSo 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. Web1. Calculate the [H 3 O +], [OH −], pH, and pOH of a 0.386 M ethylamine (C 2 H 5 NH 2 ) solution. The K b of C 2 H 5 NH 2 is 5.6 × 1 0 − 4 2. What is the percent ionization of propionic acid (CH 3 CH 2 COOH) in a solution that is 0.45 M CH 3 CH 2 COOH? The pK a of CH 3 CH 2 COOH is 4.89 .
