Reason:
Since the surface charge of particles at isoelectric point becomes les negative=>Coloumb repulsion decreases
also,binding of particles increases to some extent....[1]

yeah thats b silly meh

bt surface chrge dnt decrease it bcums zero at isoeltronic point

no surface charge wont be zero...it would be less negative,so that repulsion decreases and system becomes stable..
