Title: Equivalence point calculation with ΔV, V , pH and ΔpH given.
Post by: SeekingBoi on June 10, 2021, 01:40:46 AM

So we did a weak acid and strong base titration and we got the values of pH at many different volumes (ie, how much NaOH added to 25 mL of 0.1M of Acetic acid). How do I find the equivalence point from it is what I was wondering. Thanks in advance.

You don't.

But just by looking at the titration plot you can find the end point - look for the highest slope/most steep part of the plot.

Or, instead of titration curve. try to make a Gran plot.
