01.Solving a chemistry problem

6. A small amount of hydrogen sulfide was passed through an aqueous solution of copper sulfate until a sol was formed. Determine the charge of the particles (Z) and indicate to which electrode the counterions of the diffuse layer move in an external electric field.
1) Z0, to the anode 2) Z0, to the cathode 3) Z0, to the anode 4) Z0, to the cathode
