Therefore, lyophobic colloids are those that "fear" or do not mix well with the solvent. 2. **Characteristics of Lyophobic Colloids**: - When lyophobic colloids are mixed with a suitable liquid (solvent), there is a very weak force of attraction between the colloidal particles and the solvent molecules. This weak interaction means that the colloidal particles do not easily disperse or remain stable in the solution. ...
