How to figure out the ph of a solution
Web4 de abr. de 2024 · Calculate the pH at the equivalence point of a titration of 62 mL of 0.1 M C H X 3 N H X 2 with 0.20 M HCl. The K X b = 4.4 ⋅ 10 − 4. At the equivalence point, the moles of CH3NH2 equals the moles of HCl. This is simple solution stoichiometry. Turns out, we require 62 mL or the CH3NH2 and 31 mL of the HCl for a total volume of 93 mL.

WebThe pH is equal to 9.25 plus .12 which is equal to 9.37. So let's compare that to the pH we got in the previous problem. For the buffer solution just starting out it was 9.33. So we added a base and the pH went up a little bit, but a very, very small amount. So this shows you mathematically how a buffer solution resists drastic changes in the pH.
