How are the following colloids different from each other in respect of dispersion medium and dispersed phase? Give one example of each type.

(a) √3/√2 is the correct option

(Hint : Dispersed phase : Gas; Dispersion medium : Solid)

[Hint : D.P.                   D.M.                        Example (a) Solid/liquid           ...

[Hint : (i) Multimolecular colloids formed by aggregation of small atoms or molecules. Example, gold sol, sulphur sol. (ii) Macromolecular colloids formed by dispersing macromolecules having colloidal size in proper dispersion ...

Colloids can be classified on various bases: (i) On the basis of the physical state of the components (by components we mean the dispersed phase and dispersion medium). Depending on whether...

Multimolecular colloids: In this type of colloids, colloidal particles are aggregates of atoms or molecules each having size less than 1nm, e.g., sulphur sol, gold sol. Macromolecular colloids: In this type...

Aerosol Emulsion Hydrosol 1. Sols in which the dispersion medium is gas and dispersed phase is solid or liquid. For example: Smoke, d 1. A colloidal system in which dispersion medium and dispersed phase...

(i) Macro molecular colloids: Macromolecules in suitable solvents form solution. Where in size of the macromolecules may fall within the colloidal range. The system showing such characteristics are called macromolecular...

When the dispersion medium is water colloids are classified as hydrophilic colloids and hydrophobic colloids. Hydrophilic colloids are solvent (water) attracting, reversible and quite stable, e.g., gum, starch, gelatin etc....

(a) noble gases.  (b) between HCl molecules.  (c) Between water molecules or HF molecules.  (d)Between NO3 - and water molecules
