Assuming you know how to find the equivalence point on the titration curve, and assuming it is not [strong acid/strong base] or [weak acid/weak base], all you need to do is find the half equivalence point, which gives you the pKa of the first solution.
Then to get the Ka, you go 10-pKa .

Why weak acids are not used for titrations?
This is so because titration of a weak acid with a weak base do not give a sharp change inconductivity curve. Hence it is not possible to determine the end point from the curve.
How is the KB of ammonia calculated from the half titration point?
At half titration pH=pKa (you need the pH from the graph of your titration, y axis) ph = pKa + log (base/acid) 10^-pKa = Ka Kw=Ka*Kb Kb=Kw/Ka Ka = Kw/Kb
What is the titration curve of phenylalanine?
The titration curve of phenylanaline is around pk value 6.89 which neutral pH. It has a two buffer one in the acidic portion and the neutral one.
Why the Titration curve is varying with different with acid base titration?

How do you determine the pka of oxalic acid?
The pka of oxalic acid can be determined with the help of titration curve. The slight inflection that occurs corresponds to the first end point.

to determine the end point of titration
What is the approximate pH of the equivalence point in the titration pH curve?
Without seeing the curve, we can't answer this.
What is the Shape of titration curve for complexometric titration?
If we plot the pM (M= concentration of metal ion in the analyte) against the volume of titrant the titration curve takes the sigmoidal shape, plateau in the first part, sharp rise around the equivalence point and then again flat.
Where is the buffer region in a titration curve for the titration of a weak acid with a strong base?
It is the nearly horizontal region before the equivalence point.
What is the scout titration?
A scout titration is used to determine the approximate amount of titrant needed.
