Why are gums considered lyophilic sols?And Why are hydroxide sols considered lyophobic sol? |
|
Answer» Answer: Explanation: Basically, lyophilic colloids are solvent loving particles, and LYOPHOBIC colloids are solvent hating particles. The MAIN difference between lyophilic colloids and lyophobic colloids is that lyophilic colloids are thermodynamically stable whereas lyophobic colloids are unstable. In such solids, the DISPERSED phase does not easily precipitate and the sols are quite stable. These sols are reversible in nature. ... If water is used as the DISPERSION medium, lyophilic sols are called hydrophilic sols. Starch, gum, gelatin, egg albumin etc. are EXAMPLES of lyophilic sols. The reverse logic for hydroxide sols.. |
