Question

Isoelectric point certain pH at which concentration of the dipolar ion is :

• A. always at its minimum
• B. always at its maximum
• C. always at its zero
• D. None of the above

Answer 1

The correct option is B always at its maximum


Isoelectric point:
A certain pH at which the concentration of the dipolar ion is at its maximum and the concentrations of the anions and cations are equal.
$\text{pI (Isoelectric point) = pH at which there is no net charge}$
