101. Solving a chemistry problem
2. The coagulation thresholds with electrolytes for the sol under study turned out to be equal in mg-eq/l: NaNO3-300, Na2SO4-29, MgCl2-250. Which electrolyte ions are coagulating? What is the sign of the charge of the sol particles? Write the formula of the sol micelles, assuming that it was obtained by combining solutions of AgNO3 and KCl.
