4 How will the value of the coagulation threshold change if, for a coagulation of 10 • 10-6 m3, Ag? Instead of 1.5 • 10-6 m3 KΝO3 concentration of 1 kmol / m3 take 0.5 • 10-6 • m3 Ca (NO3) 2 concentrations of 0 , 1 kmol / m3 or 0.2 • 10-6 m3 Al (NO3) 3 concentrations of 0.01 kmol / m3? The obtained values of the coagulation threshold can be compared with the dependence on the valence of the ions established by Deryagin-Landau.
