Mixture

• CLASSIFICATION OF MATTER:

  Mixtures are combination of two or more substances that are physically mixed and can also be physically separated
• In distillation, components of liquid mixture are vaporized then condensed and collected as distillate
• In evaporation, heating the mixture of liquid and solid dissolved salts until liquid has evaporated
• Decantation is separating liquid from solid and other non-mixing liquids
• Chromatography is done when mixture is dissolved in a fluid solvent
• Homogeneous mixture has only one phase observable
• Solute is the substance dissolved
• Solvent is the dissolving agent
• Solute > solvent = concentrated solution
• solute < solvent = diluted solution
• solute = solvent: saturated solution
• higher than max allowable solute = supersaturated solution
• Heterogeneous mixture is two or more phases are observable
• HETERO

  Suspension - particles settle out
• HETERO

  Colloids - exhibits Tyndall effect
• HETERO

  Emulsions - non-mixing colloidal suspensions of one liquid in another liquid
• HETERO

  Aerosols - suspensions of fine solid particles or liquid droplets in air/gas
• HETERO

  Solid solutions are iron ore, granite, marble
