Mixtures that are not evenly mixed but cannot easily be separated by filtering -a -alloys-b-suspensions-colloids-d-solutions?
Colloids are mixtures where particles are dispersed but not dissolved in a medium, making them not evenly mixed but difficult to separate by filtering due to their small particle size. Alloys, mixtures of metals, can be evenly mixed but still difficult to separate due to their similar properties. Solutions are evenly mixed but can be separated if the components have different boiling points, while suspensions contain larger particles that can be separated by filtering.
Why are colloid important?
nothing
When colloids are filtered do they leave residue?
Yes, colloids can leave a residue when filtered. Colloids are larger particles that can be trapped by the filter, resulting in a residue left behind after filtration.
Can you differentiate colloids from solutions in terms of filter ability and stability?
Colloids cannot be separated by filtration due to their particle size being larger than in solutions. Solutions pass through filters easily due to their small particle size. Colloids are relatively stable over time compared to solutions, which may separate over time due to the solute settling at the bottom.
Are all colloids negatively charged?
No, not all colloids have a negative charge. Colloids can have a positive, negative, or neutral charge depending on the type of particles present in the dispersion and the interactions between those particles.
Can colloids be separated by filteration?
Sometimes is possible, depending on the type of the coloid; for example aerosols.

Is colloids homogenous or heterogenous?
Bricks would be considered heterogeneous mixtures. They contain various sediments that can be easily seen and can be separated again.
What are some substances separated by centrifuge?
milk , separating colloids and organic substances
Are brownies colloids?
After my opinion they are not colloids.
Colloids properties and uses?
A colloid is a homogeneous, noncrystalline substance consisting of particles of one substance dispersed through another substance. Some common colloids are gels, sols, and emulsions. Particles cannot be separated out by ordinary filtering or centrifuging and will not settle.
Why are colloid important?
nothing
How are liquid-liquid colloids like mayonnaise are called?
These colloids are called emulsions.
Is ammonia a colloid?
Colloids are a special type of solution with very small particles suspended within the solvent. Colloids frequently appear "murky" or "opaque". The particles are large enough to scatter light. You have experience with the way fog interacts with the light from car headlights. Colloids generally do not separate on standing. They are not separated by filtration. With ammonia nothing is in suspension. NH3 is not in a solution and when added to other compounds it becomes a different chemical. Example NH3 + H2O = NH4OH (Anhydrous Ammonia + Water = Ammonium Hydroxide) Ammonium Hydroxide can not be separated back to NH3 and H20 by filtration.
What are the negative effects of colloids on the environment?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
What is the visibility of colloids?
colloids are not visible due to their tiny particle size, (when the colloid is stable).
What type of mixtures are separated by centrifuges?
Centrifuges are commonly used to separate heterogeneous mixtures, such as suspensions, emulsions, and colloids. These mixtures contain particles of different sizes and densities that can be separated based on their centrifugal force during rotation in the centrifuge.
