84. How will the coagulation threshold change if for coagulation of 10⋅10-5 m3 of AgI sol instead of 1.5⋅10-6 m3 KNO3 of concentration 1 kmol/m3 we take 0.5⋅10-6 m3 Ca(NO3)2 of concentration 0.1 kmol/m3 or 0.2⋅10-6 m3 Al(NO3)3 concentration 0.01 kmol/m3? Compare the obtained coagulation threshold values with the dependence on the coagulation threshold value and compare with the dependence on the ion charge value established by Deryagin - Landau.
