Difference between Lyophilic and Lyophobic Colloids

WebThus although emulsions are lyophobic colloids they have sonic distinctive properties. If an emulsion is made empty by shaking two liquids like benzene and water or chloroform and water, the Emulsion on standing will quickly break and the two liquids will separate into two layers. This breaking of the emulsion is due to coalescence of the droplets. http://www.chem1.com/acad/webtext/states/colloids.html the thing 4k uhd
