The method of preparing colloidal solutions by chemical decomposition of compounds is called:
Dispersion
Condensation
Hydrolysis
Desolvation
Hydrolysis is the method of preparing colloidal solutions by the chemical decomposition of compounds through the reaction with water, resulting in the formation of colloidal particles.
