An example of solid solution is:

• (A) butter
• (B) gemstones
• (C) paint
• (D) hair cream

When considering the options provided, the best example of a solid solution is (C) paint. Let’s break down why paint fits this definition while the other options do not.

Understanding Solid Solutions

A solid solution is a homogeneous mixture where one or more solutes are dissolved in a solid solvent. This means that the components are mixed at the atomic or molecular level, resulting in a single-phase solid material. The most common examples of solid solutions are alloys, like bronze or steel, where different metals are combined.

Analyzing the Options

• Butter: This is an emulsion, primarily composed of fats and water. It does not represent a solid solution because it contains distinct phases.
• Gemstones: While gemstones are solid, they are typically crystalline structures that do not involve a mixture of different components at the atomic level. Each gemstone has a specific chemical composition.
• Paint: Paint is a mixture of pigments (which can be solids) suspended in a liquid medium. When it dries, the pigments form a solid layer, making it a good example of a solid solution in the context of a homogeneous mixture.
• Hair Cream: Similar to butter, hair cream is an emulsion and contains various ingredients that do not form a solid solution.

Why Paint is the Best Example

When paint dries, the liquid evaporates, leaving behind a solid film of pigment particles that are evenly distributed. This process allows the pigments to form a solid solution, where the particles are uniformly mixed, creating a consistent color and texture. The solidified paint exhibits properties that are characteristic of solid solutions, such as uniformity and stability.

Real-World Applications

Understanding solid solutions is crucial in various fields, including materials science and engineering. For instance, in creating high-performance coatings, knowing how to manipulate solid solutions can lead to improved durability and aesthetic qualities.

In summary, among the options given, paint stands out as the most fitting example of a solid solution due to its homogeneous mixture of pigments that solidifies into a uniform layer. This concept is essential in both everyday products and advanced material applications.
