Answer / s rampal
-log10[Ka] =pKa where Ka is dissociation constant and can
be calculated by using formula Ka = [H+][B-]/[HB]

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.

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.
