Which of these is an example of a solid sol?
Coloured gem
Jelly
Cheese
Smoke
Coloured gem
A solid sol is a type of colloidal dispersion where a solid is dispersed in another solid. A coloured gemstone is the perfect example, where metal oxides or other solid impurities are dispersed within a solid mineral matrix.
A solid sol is a type of colloidal dispersion where a solid is dispersed in another solid. A coloured gemstone is the perfect example, where metal oxides or other solid impurities are dispersed within a solid mineral matrix.
Think of a coloured gem like a piece of rock candy that has tiny speckles of solid dye trapped inside it while the sugar crystallizes; the dye is the dispersed phase and the sugar is the solid medium.
Remember 'SS-Sol': Solid in Solid is a Solid Sol.

In a solid sol, the dispersed phase is a solid and the dispersion medium is also a solid. This occurs when solid particles are trapped within a solid crystal lattice during formation, often resulting in characteristic colors due to the light absorption properties of the transition metal ions present as the dispersed phase.
Colloidal systems are classified based on the physical state of the dispersed phase and dispersion medium.
A solid sol maintains a rigid structure as both components are solid.
Common examples include alloys and gemstones.
High durability and aesthetic value in gemstones.
Formation is dependent on specific geological conditions and chemical impurities.
Jewelry and decorative arts.
Manufacturing of specialized alloys.
Option B (Jelly) is a gel (liquid dispersed in solid).
Option C (Cheese) is a gel (liquid dispersed in solid).
Option D (Smoke) is an aerosol (solid dispersed in gas).
A is correct тАФ A coloured gem represents a solid sol because it consists of solid particles dispersed within a solid mineral host.
For competitive exams, memorize the colloid classification table by heart; remember that smoke is 'solid in gas' (aerosol), while mist is 'liquid in gas' (aerosol).
