Homework Answers
The double layer has two layers around the object that is exposed to layer . The first layer is called as the surface charge which forms the chemical interactions with the object . And the second layer is called as the diffuse layer which is attracted by the surface charges , and is composed of ions .
ionic strength affect on electrical double layer:
The ionic strength affects the double layer greatly . Increasing the concentration ( molarity / molality) , or the valence of the counterions , the double layer gets compressed , which increases its electrical potential gradient .

The charge separation/double electric layer theory is critical in our understanding of nanoparticles’ behavior within an aqueous environment. Please use schematics to illustrate the difference between surface potential and zeta potential of a particle submerged in aqueous environment. Use simple equations to indicate how the change in solution ionic strength will affect both surface and zeta potentials.
