what are colloid ? explain the effect shown by colloidal solution with help of diagram. define brawnian motion

​

Answer 1

Question:

what are colloid ?

Answer:

a colloid is a phase separated mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture

Question:

define brawnian motion.

Answer:

Brownian motion, or pedesis, is the random motion of particles suspended in a medium. This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain

Answer 2

Answer:

Explanation:

Brownian Movement in chemistry is said to be the random zig-zag motion of a particle that is usually observed under high power ultra-microscope. This movement resembles the exact motion of pollen grains in water as explained by Robert Brown, hence, the name Brownian movement.

More significantly, Albert Einstein’s later explained the Brownian movement more clearly in his paper stating that the pollen was moved by water molecules. This discovery served as great evidence of the existence of atoms and molecules.

Understanding Brownian movement is crucial as it forms a base for the modern atomic theory. The kinetic theory of gases is also based on the Brownian motion model of particles. Additionally, the mathematical models describi
