Vedclass · Answer

(C) Hydrophilic sols (lyophilic sols) are solvent-loving and are quite stable. $1$. They have high viscosity and low surface tension compared to the dispersion medium (water). $2$. They are reversible in nature,meaning they can be reformed by simply mixing the dispersed phase and dispersion medium after coagulation. $3$. They can be prepared in high concentrations. $4$. The charge on the particles is not fixed; it depends on the $pH$ of the medium. Therefore,the statement that 'viscosity and surface tension are nearly the same as that of water' is incorrect,as hydrophilic sols generally have higher viscosity than water.

Which of the following is $NOT$ a property of hydrophilic sols?
