8. According to the table. 2 Write the structural formula of a hydrosol micelle A if substance B is a stabilizing electrolyte. Indicate the sign of the electric charge of colloidal particles. Construct for the hydrosol A the scheme of the double electric layer according to the Stern theory and the scheme of the electric potential fall in it. Explain what potential ensures the stability of the system and how it changes when electrolytes - coagulants are introduced into the system. Which of the electrolytes C introduced into the system is the most economical coagulant for the resulting sol?
Option Hydrosol A Electrolyte-stabilizer B Electrolytes-coagulants C
8 Beryllium sulfide (BeS) Beryllium nitrate (Be(NO3)2) FeCl3 Cu(NO3)2 KBr
