Solutions, suspensions, and colloids

This document discusses solutions, colloids, and suspensions. It defines solutions as formed from a solvent and solute that contain small particles that do not separate or scatter light. There are three types of solutions: unsaturated, saturated, and supersaturated. Colloids have medium sized particles that cannot be filtered but can be separated by semipermeable membranes. Examples include fog, milk, and blood plasma. They scatter light, known as the Tyndall effect. Suspensions have very large particles that settle out and can be filtered, like particles of mud in water.

Solutions, colloids and  suspensions
Solutions: Formed from solvent and solute. NaCl solution ( NaCl is a solute and  H2O is a solvent) Contain small particles (ions or molecules). • Are transparent. • Do not separate.. • Do not scatter light. •
Three types of solutions. They are: Unsaturated solution: A Solution in which the solute  concentration is lower than its equilibrium solubility. is said to be saturated when the solvent is not capable of dissolving any more solute at a particular (definite) temperature.
 Saturated solution: solution in which the maximum amount of solute has been dissolved. Any solute added to the solvent after the solution reaches its saturation point will not dissolve and will remain as a precipitate
 A solution is said to be super saturated when it contain a larger amount of the solute than it is necessary to form a saturated solution than it is necessary to form a saturated solution a particular temperature. It is said to be super saturated at that temperature. If the temperature became down/reduce it become crystal from.
Colloids Have medium size particles. • Cannot be filtered. • Can be separated by semipermeable membranes. •
Examples of colloids include Fog • Milk • Blood plasma •
Scattering of a light beam as it passes through a colloid. 
Because colloids are a dispersion of many tiny  particles in a solvent, we can see the Tyndall Effect The beam reflects off each individual particle ◦ 9 Laser beam through silver solution
Have very large particles.  Settle out.  Can be filtered.. 
 When mud is dissolved in water, particles of mud are distributed evenly in water. After some time, the particles of this solution settle under water due to influence of gravity. This solution is an example of Suspension by comparing to True Solution , particles of suspension are big enough to be seen with naked eye
