Want this question answered?
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.
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.

Without seeing the curve, we can't answer this.
It is the nearly horizontal region before the equivalence point.

example of a J-curve population in nature? Explain.
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
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 .
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.
check the graph on this site, its a typical example of what to expect. http://terpconnect.umd.edu/~toh/models/TitrationDemo.html
