5. Solution to Chemistry Problem
1. Based on the data in the table, 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 electrode potential drop. Explain what potential ensures the stability of the system and how it changes when electrolyte C, a coagulator, is introduced into the system. Which of the electrolytes C introduced into the system causes the most economical coagulation for the resulting sol?
Option Hydrosol A Stabilizer electrolyte B Coagulant electrolyte C
1 Lead sulfate (PbSO₄) Sulfuric acid (H₂SO₄) NaCl; K₂SO₄; NH₄NO₃
