38. Solution to Chemistry Problem

9. According to the data in Table 2, write the structural formula of a micelle of hydrosol A if substance B is an electrolyte stabilizer. Indicate the sign of the electric charge of the colloidal particles. Construct a diagram of the double electric layer for hydrosol A according to the Stern theory and a diagram of the electric potential drop 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
9 Strontium fluoride (SrF2) Sodium fluoride (NaF) FeCl3; Cu(NO3)2 KBr
