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 9, 2019, 4:11 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.
