How you can calculate pKa ?..

Answer / pratap rasam

Carry out acid-base titration and note down the
readings.Plot a graph of pH nersus volume of titrant added.
Locate the equivalence point. Compute the volume exactly
half the equivalent point and from this volume
corresponding pH is nothing but pKa.

How you can calculate pKa ?..

Answer / bhupalreddy

The equation for pKa is this:

Presuppose you have a compound HX is

HX --> H+ + X-
pKa = -log Ka

To find the Ka:
Ka = [H+] x [X-]/[HX]

Ka (is dissociation constant) is always products over
reactants.
