Among these substances that are included in the mixture are – It is a sol-colloid system where the substance is dispersed and the dispersing medium is a liquid. The suffix “phobe” comes from phobia which means “fear” or avoidance. While the ending “fil” in lyophil means “like, happy” or close, so lyophil is a colloidal system whose particles attract solvent molecules.
Aerosols are colloidal systems containing solid or liquid particles in a gaseous dispersion medium. Examples are fog, dust, clouds, smoke and hair follicles.
Among these substances that are included in the mixture are
Keywords: Among the following substances that are not colloidal systems, air, air, lyophilic, lyophobic, aerosol, sol, gel, gel, mist, vapour, cloud, oil,
Examples of Differences in Compounds and Mixtures and Their Utilization
New Questions in Chemistry Some ferric chloride compounds are yellow while others are green. If the yellow is reacted with dilute sulfuric acid, a new compound will be formed because the acid that reacts is stronger than the acid produced. Reacting acids: some ferric chlorides are yellow and some are green. If we react yellow with dilute sulfuric acid, a new compound is formed because the acid that reacts is stronger than the acid from which it was formed. feedback: * 1 point A. H2SO4B. H2SC. HCLD.
