Can you give me some examples of Lyophilic and Lyophobic colloids?

Dear Student
Examples of lyophilic sols include sols of gum, gelatine, starch, proteins and certain polymers in organic solvents.
Examples of lyophobic sols include sols of metals and their insoluble compounds like sulphides and oxides. Lyophobic sols need stabilizing agents to keep the dispersed phase from precipitating out.
We hope that clarifies your query.
