Question

what causes charge on sol particles

Answer 1

The origin of the charge on the sol particles in most cases is due to the preferential adsorption of either positive or negative ions on their surface. The sol particles acquire electrical charge in any one or more of the following ways. ... (ii) The dispersion medium must also get some charge, because of the friction

Answer 2

The cause for charge on sol particles can be explained as:

•Sol particles develops electrical charges due to dissociation of surface molecules.

•Sols may be either positively or negatively charged .

•This charge can be balanced by oppositely charged ions in the sol.

•Sol is a type of coloid in which the dispersed phase is solid and dispersed medium is liquid .

•Gel,starch,water are some of the examples for sol.
