Recall that solutions are homogeneous mixtures. For example, sodium chloride does not settle out when its solutions remain constant.
Yes, a solution can settle over time. This settling process occurs as the particles in the solution separate and sediment to the bottom due to gravity. To prevent settling, the solution can be continuously stirred or shaken.
Colloids contain particles that are larger than those in a solution but smaller than those in a suspension. Suspensions have particles that are large enough to settle out over time, unlike solutions where particles are uniformly dispersed and do not settle. Solutions have the smallest particle size and the particles do not settle or scatter light.
Both solutions and suspensions are mixtures of two or more components. However, the particles in suspension are larger and will eventually settle out, where the particles in a solution are on the atomic or molecular level.
Colloids have particles that are intermediate in size between solutions and suspensions and do not settle out over time like suspensions. In a solution, the solute particles are evenly distributed and do not settle out, whereas in a suspension, the solute particles are larger and settle out over time.
In chemistry, a sol is a type of colloid solution where solid particles are dispersed in a liquid. It differs from other types of solutions, like suspensions or emulsions, because the particles in a sol are smaller and do not settle out over time.
Suspension
A homogenous mixture of two or more substances that are not solutions is a colloid. Colloids have particles that are larger than the particles in a solution, but still do not settle out over time. Examples of colloids include milk and fog.
Particles in solutions are evenly distributed and small enough to not settle out or be filtered out easily. In contrast, particles in suspension are larger and will settle out over time or with filtration. Solutions are typically clear, while suspensions may appear cloudy or opaque due to the presence of suspended particles.
The three kinds of mixtures are solutions (uniform mixture with solute dissolved in solvent), colloids (uniform mixture with larger particles that do not settle), and suspensions (non-uniform mixture with larger particles that settle over time).
Yes, mixtures can be classified as solutions, suspensions, or colloids based on the size of the particles present. Solutions have particles that are very small and do not settle out, suspensions have larger particles that eventually settle, and colloids have intermediate-sized particles that do not settle but scatter light.
In science, a solution is a homogenous mixture composed of two or more substances. Solutions are transparent and do not settle over time. They are made up of a solute (substance being dissolved) and a solvent (substance in which the solute is dissolved).
