Suspension vs. Colloid: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A suspension contains larger, non-dissolved particles that settle over time, whereas a colloid has smaller, evenly distributed particles that don't settle.
Key Differences
Suspension is a heterogeneous mixture where particles are larger and eventually settle at the bottom due to gravity. Colloid is a mixture where particles are smaller and remain distributed throughout the solution, providing more stability with no settling.

In suspension, the particles are typically larger, typically over 1000 nanometers, making them visible and leading to sedimentation. In a colloid, particle size ranges from 1 to 1000 nanometers, which is too small to be seen individually but large enough to scatter light (Tyndall effect).

In a suspension, particles are visible to the naked eye, and the mixture can be separated by filtration. In a colloid, particles are not visible, and the mixture cannot be easily separated through ordinary filtration.

An example of a suspension is mud in water, where particles eventually settle. In contrast, milk is a colloidal mixture where fat globules are dispersed in water and do not settle.

Suspensions are often used in pharmaceuticals for oral suspensions of drugs, while colloids are used in many food products, cosmetics, and industrial applications due to their stability.

Repeatedly Asked Queries
What is a suspension?
A suspension is a heterogeneous mixture in which solid particles or liquid droplets are dispersed in a liquid or gas, but they eventually settle out over time.

Shumaila Saeed
Dec 08, 2023
Can you filter a suspension to separate its components?

Shumaila Saeed
Dec 08, 2023
Can you separate the components of a colloid by filtration?
Filtration alone is usually not effective in separating the components of a colloid because the particles are too small to be trapped by a filter.

Shumaila Saeed
Dec 08, 2023
Are suspensions and colloids both heterogeneous mixtures?
Yes, both suspensions and colloids are heterogeneous mixtures because their components are not uniformly distributed.
Shumaila Saeed
Dec 08, 2023
Is a suspension transparent or opaque?
Suspensions are typically opaque or cloudy because of the visible particles within them.
Shumaila Saeed
Dec 08, 2023
How does a colloid differ from a suspension?
Colloids have smaller particles that remain suspended for a more extended period and do not settle out like the larger particles in a suspension.
Shumaila Saeed
Dec 08, 2023
What is the key difference between a suspension and a colloid?
The key difference is that suspensions have larger and less stable particles that settle out, while colloids have smaller, more stable particles that remain dispersed.
Shumaila Saeed
Dec 08, 2023
What is a colloid?
A colloid is a type of heterogeneous mixture in which fine solid particles or liquid droplets are evenly dispersed in another substance, typically a liquid, creating a stable and semi-transparent solution.
Shumaila Saeed
Dec 08, 2023
Which is more stable, a suspension or a colloid?
Colloids are generally more stable than suspensions because their particles are smaller and less likely to settle.
Shumaila Saeed
Dec 08, 2023
Do suspensions and colloids have practical applications?
Yes, both suspensions and colloids have numerous practical applications in various industries, including medicine, food, and cosmetics.
Shumaila Saeed
Dec 08, 2023
Can you see individual particles in a colloid with the naked eye?
In most cases, individual particles in a colloid are too small to be seen with the naked eye, making the mixture appear uniform.
