Carbon dioxide dissolves in water.
Air is an example of a gas-gas solution.
A solution can exist as a solid, liquid, or gas. Examples include alloys (solid solutions), soda (liquid solution), and air (gas solution). Solutions are defined as homogenous mixtures of two or more substances.
No, not all solutions are liquids. Solutions can be liquids, gases, or solids. For example, air (a gas solution of oxygen, nitrogen, and other gases) and brass (a solid solution of copper and zinc) are both examples of solutions that are not in liquid form.
Give an example of a mechanical mixture or solution that is made of: (b) two or more liquids
An example of a liquid-gas solution is carbonated water, where carbon dioxide gas dissolves in water. An example of a gas-gas solution is air, which is a mixture of various gases like nitrogen, oxygen, carbon dioxide, and others in the atmosphere.
A solution is a homogeneous mixture of two or more liquids, only one phase. When another phase exist (for example solids, immiscible liquids) this is not a true solution.
Soda is an example of a liquid-gas solution, as it contains carbon dioxide (a gas) dissolved in water (a liquid).
There are a number of examples of solid in gas solutions, such as smoke, in which carbon and air are in the form of a solution. Automobile exhaust is another example of solid in gas solution. An example of such solution is Iodine vapors in the air.
Soda is an example of a liquid-gas solution, as it contains carbon dioxide (a gas) dissolved in water (a liquid).
An example of a solid and gas solution: hydrogen dissolved in palladium.
