83. How many times will the sol coagulation threshold decrease if for coagulation instead of 0.5 kmol/m3 NaCl (it requires 1.2⋅10-6 m3 per 10⋅10-6 m3 of sol) use 0.036 kmol/m3 MgCl2 (0. 4⋅10-6 m3 per 10⋅10-6 m3 sol) and 0.01 kmol/m3 AlCl3 (0.1⋅10-6 m3 per 10⋅10-6 m3 sol) ? Compare the obtained values of γ with the dependence of the coagulation threshold on the ion charge, established by Deryagin-Landau.
