Yes, it was first observed by Robert Brown in 1827, and it is random movement of particles suspended in a fluid or gas.
Brownian motion is the random moving and mixing of particles.
One difference is the size of particles: in a solution, particles are uniformly dispersed at a molecular level, whereas in a colloid, particles are larger and dispersed throughout the mixture but do not settle out.
Colloid has larger particles compared to solution, but smaller than suspension. Therefore, of the three options listed (compound, colloid, suspension), a compound mixture typically has the smallest particles.
Depending on the particles dimension: - between 1 and 1000 nm is a colloid - above 1000 nm is a suspension - the solution hasn't visible particles
No, it is a salt. I water it forms a solution.
Brownian motion of particles in a colloid is caused by random collisions with solvent molecules. These collisions result in erratic movement of the particles within the colloid due to thermal energy. Brownian motion helps to keep the particles suspended and well dispersed within the colloid.
Brownian motion is the random moving and mixing of particles.
A colloid has particles small enough that they will never settle out; brownian motionkeeps them in suspension. A colloid shows the Tyndall effect. An emulsion or suspension has droplets or particles which, due to their larger size, separate from a suspension.to form a layer or precipitate.

a colloid has smaller particles than a solution
A homogeneous solution contain ions or molecules.A colloid contain insoluble particles in the range 1-1000 nm.
A colloid is a solution where the particles inside it are between 1 and 1000 nanometers in diameter. The particles inside the solution are evenly dispersed throughout the solution and do not precipitate out.

A colloid. The particles do not settle out, but stay suspended.
