Solid sol is a type of colloidal solution where a solid is dispersed in a solid medium. It is a heterogeneous mixture that consists of a solid solute particles dispersed in a solid solvent. Among the given options, colored gemstones are an example of solid sol.
Explanation:
Colored gemstones, such as diamonds, rubies, emeralds, and sapphires, are formed through a process called crystallization. During the crystallization process, various impurities or trace elements get incorporated into the crystal lattice structure, resulting in the characteristic color of the gemstone. These impurities are known as color centers.
In a colored gemstone, the gem material itself acts as the solid solvent, while the impurities or color centers are the solid solute particles. The color centers are responsible for the unique colors observed in different gemstones.
In a solid sol, the dispersed particles are typically much smaller than the particles in a suspension or a colloid. The size of the solid solute particles in colored gemstones is on the atomic or molecular scale, making them extremely small and dispersed evenly throughout the crystal lattice.
The solid sol nature of colored gemstones is evident when light passes through them. The interaction of light with the color centers in the gemstone results in the absorption and reflection of specific wavelengths, giving rise to the characteristic color of the gemstone.
In conclusion, colored gemstones are an example of solid sol because they consist of solid solute particles (color centers) dispersed in a solid solvent (gem material). The solid sol nature of colored gemstones is responsible for their unique and vibrant colors.
