Write an example of: 1. Solid-solid mixture. 2. Solid-liquid mixture. 3. Liquid-liquid mixture. 4. Gas-liquid mixture. 5. Gas-gas mixture. 6. Gas-solid mixture
The Correct Answer and Explanation is:
Here are examples of different types of mixtures along with detailed textbook-style explanations:
1. Solid-Solid Mixture
Example: Brass (a mixture of copper and zinc)
Explanation:
A solid-solid mixture consists of two or more solid substances that are physically combined but not chemically bonded. In brass, copper and zinc are melted, mixed together, and then allowed to cool, forming a homogeneous alloy. This mixture has uniform properties throughout and is commonly used in hardware and decorative items. Although the components retain their individual chemical properties, they cannot be easily separated once mixed.
2. Solid-Liquid Mixture
Example: Salt water (salt dissolved in water)
Explanation:
A solid-liquid mixture occurs when a solid is mixed with a liquid and the solid either dissolves or remains suspended. In the case of salt water, salt (solid) dissolves completely in water (liquid), forming a homogeneous solution. The dissolved salt ions are uniformly distributed, making it a true solution. This type of mixture is common in everyday life, especially in cooking and science experiments.
3. Liquid-Liquid Mixture
Example: Vinegar and water
Explanation:
A liquid-liquid mixture involves two or more liquids mixed together. Vinegar, which contains acetic acid, mixes uniformly with water, forming a homogeneous mixture. In such mixtures, the components are miscible, meaning they can mix in any proportion without separating. This type of mixture is often used in cooking and cleaning solutions.
4. Gas-Liquid Mixture
Example: Carbonated water (carbon dioxide in water)
Explanation:
In a gas-liquid mixture, a gas is dissolved in a liquid. Carbonated water contains carbon dioxide gas dissolved in water under pressure. When the bottle is opened, the pressure is released and gas escapes as bubbles. This is an example of a homogeneous mixture when sealed and a heterogeneous one once opened. This type is common in sodas and sparkling beverages.
5. Gas-Gas Mixture
Example: Air (mixture of nitrogen, oxygen, carbon dioxide, etc.)
Explanation:
A gas-gas mixture is made of different gases mixed together. Air is a classic example, containing about 78% nitrogen, 21% oxygen, and small amounts of other gases. It is a homogeneous mixture because the gas molecules are evenly distributed and cannot be distinguished from one another. Gas-gas mixtures are essential for respiration and combustion processes.
6. Gas-Solid Mixture
Example: Dust in air
Explanation:
A gas-solid mixture consists of solid particles suspended in a gas. Dust in air is a heterogeneous mixture, where tiny solid particles like pollen, soot, or dirt are scattered throughout the air. These particles are visible under certain conditions (e.g., sunlight) and can be filtered out. This type of mixture is common in polluted environments or dusty rooms.
Each of these mixtures illustrates how different states of matter can combine in physical ways, leading to a variety of uses in science, industry, and daily life.
