Answer : isoelectric point
Explanation :
The $\;H^{+}\;$ ions concentration at which the colloidal particles are neither positively charged nor negatively charged (i . e ; are electrically neutral) is known as isoelectric point of a colloid .
For example , for gelatin , isoelectric point is at pH = 4.7 . At this point the colloids do not migrate under the influence of electric field . At this point , the lyophilic colloids are expected to have minimum stability .
