WebIn most cases, coagulation occurs as a result of the accumulation of electrolytes in the bloodstream. In the presence of an electrolyte, the particles of a colloidal solution are neutralised by the particles of an electrolyte that have opposite charges to the particles of the colloidal solution. WebThe coagulation value in millimoles per liter of electrolytes used for the coagulation of A g 2 O 3 are as given I. N a C l = 5 2 II. K C l = 5 III. B a C l 2 = 0. 6 9 IV. M g S O 4 = 0. 2 2 The correct order of their coagulating power is : Stability of lyophilic sol depends on the following two factors 1. Charge on the colloidal particles 2. Solvationof the colloidal particles When the charge and solation layers are disturbed or removed, are removed then only lyophilic sols can be coagulated. This can be done by either adding an electrolyteor a … See more Substances like metals, their sulfides etc cannot be simply mixed with the dispersion medium to form a colloidal solution.
