Weak Acid Titrations: Calculate pH at the Midpoint

In this video we’ll work through an example showing how to determine pH at the midpoint for a weak acid titrated with a strong base. First, we’ll set up a mmol reaction table. Then we’ll evaluate the E row of this mmol table to determine where the reaction is along the titration curve. Based on the specific region of the titration curve, which will be the midpoint for this video, we can then calculate the pH of the solution.
