dear, refer. https://www.homeworklib.com/question/1530881/for-the-diprotic-weak-acid-h2a-ka1-40-10-6-and
We're asked to find the pH of 50mL of .1 M of a weak acid (labeled HX), before we add any .1 M NaOH. The Ka is 1.5e-5. The pH I found was 4.00 (feel free to fact check me). Here's the part I need help with: -We are also asked to find the pH of the solution at the "endpoint". Not sure what this means. Do they mean equilibrium? If so, how would I calculate this? Thanks.
calculating the ph of a weak acid titrated with a strong base
An analytical chemist is titrating 241.7 ml of a 0.9100 M solution of propionic acid (HCH.CO) with a 0.4200 M solution of KOH. The pk of propionic acid is 4.89. Calculate the pH of the acid solution after the chemist has added 602.4 ml of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus...

This problem deals with Acid-base titrations and pH scale for a weak acid and a weak base. Calculate the pH of the solution that results from adding 7.5 [ml] of Ammonia (NH3) to a beaker that contains, 100 ml of distilled water and 15 ml of 0.1 M Acetic acid (HC2H3O2). A buret containing 50 mL of 0.1 M Ammonia (NH3) is being used as the titrant. The beaker containing 100 ml of distilled water, and 15 ml of 0.1...
