Describe a solution,suspension, and colloid

The components of a mixture can be separated without chemical reactions.

how is a colloid desting from a solotion?

A solution, suspension, and colloid are three types of mixtures, each with different characteristics based on the size and nature of the particles involved.

1. Solution: A solution is a homogenous mixture composed of two or more substances that are evenly distributed on a molecular level. In a solution, the solute (the substance being dissolved) is uniformly dispersed in the solvent (the substance doing the dissolving). The solute particles are too small to be seen by the naked eye or even using a microscope. Examples of solutions include saltwater (solute: salt, solvent: water), sugar dissolved in coffee (solute: sugar, solvent: coffee), and air (a mixture of gases like oxygen, nitrogen, and carbon dioxide). To identify a solution, you can look for a transparent appearance, as the particles are too small to scatter light.

2. Suspension: A suspension is a heterogenous mixture composed of solid particles dispersed in a liquid or gas medium. In a suspension, the particles are larger and do not dissolve in the solvent but are rather suspended within it. Due to the larger size of the particles, they can be seen with the naked eye and can settle over time if left undisturbed. If the mixture is agitated or stirred, the particles will temporarily disperse, but they will eventually settle again. Examples of suspensions include muddy water (mud particles suspended in water) and orange juice with pulp (pulp particles suspended in liquid).

3. Colloid: A colloid is a mixture intermediate between a solution and a suspension. In a colloid, the particles are larger than those in a solution but smaller than those in a suspension. The particles are dispersed throughout the solvent, but they do not settle due to their small size and the constant random motion caused by collisions with the surrounding molecules. Colloids exhibit the Tyndall effect, which means that light is scattered by the dispersed particles when passing through the mixture. This scattering of light makes the colloid appear cloudy or murky. Examples of colloids include milk (fat globules dispersed in water), gelatin (protein chains dispersed in water), and aerosol sprays (tiny liquid or solid particles dispersed in gas).
