What is the 1/2 neutralization point on this curve?
from the graph neutralization point = 15ml.
At half neutralization point pH = pKa
here neutralization point is given
Half neutralization point =
= 15ml/2 = 7.5ml
therefore half neutralisation point = 7.5ml.
in generally for weak acids
at half neutralization point concentration of weak acid = concentration of its conjugate base
for weak bases
at half neutralization point concentration of base = concentration of its conjugate acid
