The solute-like component or the dispersed particles in a colloid form the _____.
Show answer & explanation
Correct answer: B
Explanation
Explanation:
A colloidal solution is a heterogeneous mixture consisting of two main components:
Dispersed Phase: This is the component that acts as the solute and is dispersed as tiny particles. This is what your question asks about.
Dispersion Medium: The component in which these particles are dispersed (like the solvent).
Additional Facts (Important Points):
Some information about colloids that is often asked in exams:
Particle Size: Colloidal particles typically range in diameter from 1 nm to 1000 nm.
Tyndall Effect: When a beam of light passes through a colloid, the particles scatter the light, making the path of light visible.
Brownian Motion: The zig-zag motion of colloidal particles is called Brownian motion, which keeps the colloid stable.
Possible questions for the upcoming exam:
Question: Milk is an example of what type of colloidal system?
Answer: Emulsion - where liquid is dispersed in liquid.
Question: What is the process of colloidal particles moving in a continuous zigzag path called?
Answer: Brownian Motion.
Question: What is the dispersion medium in shaving cream?
Answer: Liquid (gas dissolved in liquid, which is called 'foam').
