2. Zinc sulfide sol was obtained by reacting solutions of ZnCl2 and Na2S. Determine the sign of the charge of the colloidal particle, check the feasibility of the Deryagin-Landau equation, write the formula of the micelle if 10 ml of sol was consumed for coagulation:
Electrolyte KCl K2CrO4 MgCl2 K3PO4
C, mol/l 5.0 0.1 2.5 0.01
V, ml 3.6 3.0 3.6 2.5
