Summary of Colloids for Kerala Board Class 12 Chemistry. Key concepts, important points, and chapter overview.
Overview
Colloids are a fascinating state of matter that exists between true solutions and suspensions. The term 'colloid' comes from the Greek words 'kolla' (glue) and 'oids' (like), meaning glue-like. These systems contain particles ranging from 1 to 100 nanometers in size and play crucial roles in our dai
Key Concepts
True solutions have particles smaller than
True solutions have particles smaller than 1 nm, colloids have particles between 1-100 nm, and suspensions have particles larger than 100 nm. This siz
Every colloidal system has two phases
Every colloidal system has two phases: dispersed phase (substance in smaller proportion with colloidal-sized particles) and dispersion medium (the con
Lyophilic colloids (solvent
Lyophilic colloids (solvent-loving) form easily by direct mixing and are reversible and stable (e.g., starch, gelatin). Lyophobic colloids (solvent-ha
The continuous random zig
The continuous random zig-zag movement of colloidal particles caused by unequal bombardment of dispersion medium molecules from different directions.
The scattering of light by colloidal
The scattering of light by colloidal particles makes the light beam visible when passed through a colloidal solution. This occurs because colloidal pa
