1. When two aqueous solutions are mixed, a sol or suspension is formed. The volumes of solutions are V1 and V2, and the concentrations of dissolved substances are c1 and c2, respectively. Using the Faience-Panet rule, determine the sign of the charge of the resulting particles:
Option Solution 1 Solution 2
Substance c1 V1, ml Substance c2 V2, ml
II AgNO3 1.0 g/l 50 KBr 1.0 g/l 50
