These suspensions are heterogeneous mixtures composed of relatively large particles that are visible (or that can be seen with a magnifying glass). They are cloudy, and the suspended particles settle out after mixing. On the other hand, when we make a solution, we prepare a homogeneous mixture in which no settling occurs and in which the dissolved species are molecules or ions. Solutions exhibit completely different behavior from suspensions. A solution may be colored, but it is transparent, the molecules or ions are invisible, and they do not settle out on standing. A group of mixtures called colloids (or colloidal dispersions) exhibit properties intermediate between those of suspensions and solutions (Figure \(\PageIndex\): Examples of Colloidal Systems Dispersed Phase Dispersion Medium Common Examples Name solid gas smoke, dust — solid liquid sta...

Concept: Properties of a colloid- • A colloid is a heterogeneousmixture. • The size of solute particles of a colloid is toosmall (10 -7m) to be individually seen by nakedeyes. • So, solute particles cannot be seen by naked eyes. • Colloids are big enough to scatter a beam of lightpassing through it andmake its path visible. • This is also known as Tyndall Effect. Types of Colloid Dispersed Dispersing Medium Type of colloid Few Examples Solid Liquid Sol Milk of magnesia Solid Gas Aerosol smoke Solid Solid Solid Sol Gemstone Liquid Liquid Emulsion Milk Liquid Gas Aerosol Fog, cloud Liquid Solid Gel Cheese, butter Gas Liquid Foam Shaving cream Gas Solid Foam sponge Explanation • So, fog is an example of liquid in gas. • It is formed when water vapours in the atmosphere condense and mix with the air. • If this fog mixes with smoke, it becomes smog which is very harmful for health. The correct option here isLiquid in gas.

S11.2.3 (a) The process is endothermic as the solution is consuming heat. (b) Attraction between the K + and \(\ce\) ions is stronger than between the ions and water molecules (the ion-ion interactions have a lower, more negative energy). Therefore, the dissolution process increases the energy of the molecular interactions, and it consumes the thermal energy of the solution to make up for the difference. (c) No, an ideal solution is formed with no appreciable heat release or consumption. S11.2.6 Heat is released when the total intermolecular forces (IMFs) between the solute and solvent molecules are stronger than the total IMFs in the pure solute and in the pure solvent: Breaking weaker IMFs and forming stronger IMFs releases heat. Heat is absorbed when the total IMFs in the solution are weaker than the total of those in the pure solute and in the pure solvent: Breaking...
