I can find the initial pH of the solution, but I am not given any initial volumes so can you point me in the right direction of how to solve this problem? If I don't need volumes can you give me a hint as to how this problem should be solved?© BrainMass Inc. brainmass.com October 24, 2018, 5:54 pm ad1c9bdddf
You can do this only by considering the proportions of acid and alkali. Given the concentrations, the equivalence point will be when the volume of added alkali is 50% of the initial volume of acid. With 25% alkali we find the half-neutralized point where the pH = pKa (i.e 4.76 for this acid). You have already found the pH at ...
This solution provides a detailed response which indicates how this problem can be solved when the volumes in the experiment are unknown. This is done in about 250 words.
Titration Curve of a Weak Acid with a Strong Base
A 30 mL sample of 0.35 M of lactic acid is titrated with a 0.25 M NaOH solution. Calculate the pH before NaOH is added. After 20 mL of NaOH is added. After 42 mL. After 45 mL. After 60 mL. After 80 mL. Graph the titration curve.View Full Posting Details
