What are colloids suspensions and solutions?
Colloids
| Solutions | Colloids | Suspensions |
|---|---|---|
| Do not separate on standing | Do not separate on standing | Particles settle out |
| Cannot be separated by filtration | Cannot be separated by filtration | Can be separated by filtration |
| Do not scatter light | Scatter light (Tyndall effect) | May either scatter light or be opaque |
What are some examples of solutions Colloids and suspensions?
11.7: Colloidal Suspensions
| Type of Mixture | Approximate Size of Particles (nm) | Examples |
|---|---|---|
| solution | < 2 | air, white wine, gasoline, salt water |
| colloid | 2–500 | smoke, fog, ink, milk, butter, cheese |
| suspension | 500–1000 | muddy water, hot cocoa, blood, paint |
What is difference between colloidal solution and suspension solution?
Colloidal solutions are the type of mixture, where the solute (tiny particles or colloids) is uniformly distributed in the solvent (liquid phase). The suspension is the mixture, where the solute does not get dissolved, rather get suspended in the liquid and float freely in the medium. Sugar solution in water.
How can you determine a mixture from a solution suspension or a colloid?
A solution is a homogeneous mixture of two or more substances, a suspension is a heterogeneous mixture containing particles that will settle out of solution, and a colloid is a heterogeneous mixture that contains particles that do not settle out of solution.
How big are particles in a suspension and a colloid?
Solution, Suspension and Colloid. The size of particles in a solution is usually less than 1 nm. Size of particles in a suspension is usually larger than 1000 nm. In a colloid, the particles never settle down. Hence, the Tyndall effect is always observed in colloids.
How are suspensions different from solutions and solutions?
A solution cannot be filtered but can be separated using the process of distillation. A suspension is cloudy and heterogeneous. The particles are larger than 10,000 Angstroms which allows them to be filtered. If a suspension is allowed to stand the particles will separate out. A colloid is intermediate between a solution and a suspension.

Which is intermediate between a solution and a suspension?
A colloid is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not. Colloids can be distinguished from solutions using the Tyndall effect.
