128. Solving a chemistry problem
The electrolyte coagulation thresholds for the AgI sol turned out to be equal (mmol/l): y(KCl)=256; y(Ba(NO3)2)=6.0; y(Al(NO3)3)=0.067; y(KNO3)=260; y(Sr(NO3)2)=7.0; How is a colloidal sol particle charged? Calculate the coagulating capacity of each of the electrolytes.
