1 mole of Agl//Ag^+ sol. Is coagulated by :

A mol of [Ag]Ag^(+) sol cagulated by :

In a colloidal state, the particle size of he dispersed phase ranges between 10^(3) to 10^(6) pm and the colloidal sol is of heterogeneous nature. Depending upon the ease with which these sols are formed, the colloidal sols are cassified as lyophilic and lyophobic. THe stability of a colloidal sol is due to the presence of charge on the sol particles and the neutralisation of the same is known as coagulation or precipitation. The coagulationg power of the active ions of he electrolytes can be compared with the help of Hardy-Schulze Law. The protecting power of the lyophilic sols can be compared with the help of gold number. Lesser the value of gold number, more will be the protecting power of the lyophilic sol [AgI]I^(-) colloidal sol can be coagulated by the addition of a suitable action. 1 mol of [AgI]I^(-) required mole of AgNO_(3), Pb (NO_(3))_(2) and Fe(NO_(3))_(3) as:
