IF THE COMPOUND PKA IS 5.3 WHY WE ARE ADJUSTING PH+/-2 OF THE COMPOUNDS PKA. WHAT IS THE CONDITION..

Answer / ramya sarma

pKa=pH+log [un ionised]/[ionised]
at the half neutralisation point
un ionised concentration= ionised concentration

so pKa=pH+log1
pKa=pH because log1=0

if we didnt adjudt pH +/-2.0 we may get peak split because
for un ionised we get one peak and ionised we get one more
peak
