Why only lyophobic colloids show tyndall effect?
Lyophobic colloids have particles that repel the dispersion medium, preventing them from easily mixing. This causes the particles to scatter light, which is why they exhibit the Tyndall effect. In lyophilic colloids, the particles have an affinity for the dispersion medium and do not scatter light as effectively.
A mixture can be classified as a solution suspension or colloid based on .?
Colloids are classified frequently as solutions because the particles have very small dimensions.
What does the tyndall test confirm?
The Tyndall test confirms the presence of colloids in a solution by detecting the scattering of light. It is a qualitative test used to differentiate between solutions containing colloids and solutions containing only dissolved particles.
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.
What causes Brownian motions in colloids?
Brownian motion in colloids is caused by the random collisions of solvent molecules with colloidal particles. The particles are constantly bombarded by solvent molecules, inducing them to move randomly in all directions. This motion is a result of the thermal energy of the solvent molecules, which causes the colloidal particles to exhibit a continuous zig-zag movement.
Can the Brownian motion be detected in colloids?
yes
Are brownies colloids?
After my opinion they are not colloids.
Do suspensions show Brownian motion?
Yes, suspended particles in a fluid show Brownian motion. This is the random movement of particles due to collisions with solvent molecules. Brownian motion is a direct result of the thermal energy present in the system.

How are liquid-liquid colloids like mayonnaise are called?
These colloids are called emulsions.
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...
A mixture can be classified as a solution suspension or colloid based on .?
Colloids are classified frequently as solutions because the particles have very small dimensions.
What is the visibility of colloids?
colloids are not visible due to their tiny particle size, (when the colloid is stable).

Is pizza a colloids?
no
Butter toothpaste paint whipped cream and frogs are all colloids?
Frogs are not colloids, they are amphibians.
