Determine what volume of aqueous solutions of electrolytes was added to 10.0 ml of arsenic sulfide hydrosol, if the threshold of electrolyte coagulation, the indicated concentration was equal to:
Electrolyte NaCl BaCl2 AlCl3
C, mol/l 5.0 0.4 0.01
, mol/l 5.2 0.08 0.007
Determine the sign of the charge of the colloidal particle. Write the micelle formula of the As2S3 sol obtained by passing hydrogen sulfide through a dilute solution of As2O3 arsenic oxide.
