128. Solving a chemistry problem

Magnesium carbonate sol was obtained by double exchange reaction of 14 ml of 0.05 N sodium carbonate solution and 15 ml of 0.05 N magnesium sulfate solution.
Write the molecular equation of the reaction, the full ionic equation, determine the stabilizer substance, make the formula for the structure of the MgCO3 sol micelle (indicate the aggregate, core, potential-determining (PO) and counterions (PI), diffuse layer).
For which of the electrolytes sodium chloride, potassium sulfate, calcium nitrate. aluminum chloride will have a greater coagulation threshold? Write the equation for the dissociation of salts, indicate the coagulating ions and draw the appropriate conclusions.
