Statement A: Brass is a solution while gun powder is notStatement B: A...
Brass is a homogeneous mixture of copper and Zinc. Gun powder is not a powder is a simple mixture of saltpeter, sulfur and charcoal.
Air is an example of a solution (gaseous solution) because it is a homogeneous mixture of different gases like oxygen, nitrogen, helium, hydrogen, etc.

Statement A: Brass is a solution while gun powder is notStatement B: A...
Brass is a solution while gunpowder is not. In terms of science, air represents a solution. The correct statement among the two is Statement B, which states that air represents a solution in terms of science.
Brass as a Solution
- Brass is a metallic alloy made from copper and zinc.
- It is considered a solution because it is a homogeneous mixture of two or more substances, where the copper and zinc atoms are uniformly distributed throughout the material.
- The properties of brass are different from those of its individual components, copper and zinc.
- The composition of brass can vary, with different ratios of copper and zinc resulting in different properties and characteristics.
Gunpowder as a Non-Solution
- Gunpowder, on the other hand, is not a solution. It is a mixture of sulfur, charcoal, and potassium nitrate (saltpeter).
- Gunpowder is a heterogeneous mixture, meaning its components are not uniformly distributed throughout the material.
- The sulfur, charcoal, and potassium nitrate particles are distinct and can be easily separated.
- Gunpowder is used as an explosive due to its combustion properties, but it does not exhibit the characteristics of a solution.
Air as a Solution in Terms of Science
- Air is a mixture of gases, primarily nitrogen (about 78%), oxygen (about 21%), and other trace gases.
- In terms of science, air can be considered a solution because it is a homogeneous mixture of different gases.
- The gases that make up air are uniformly distributed throughout the atmosphere.
- Like brass, the properties of air are different from those of its individual components.
- Air is essential for life on Earth and plays a crucial role in various scientific phenomena and processes.
Conclusion
- Based on the given statements, Statement B is true, which states that air represents a solution in terms of science.
- Statement A is incorrect, as brass is a solution but gunpowder is not.
- Therefore, option 'A' is the correct answer.
Statement A: Brass is a solution while gun powder is notStatement B: A...
Air is a solution as it 's composition of gases is uniform and it's particles are small in size
