DESCRIPTION

Solute and Solvent. Mixtures and Solutions. Matter. Heterogeneous materials - can see two parts. Homogeneous materials can see only one thing - one set of properties. Homogeneous mixtures Theyre mixed together so well you only see one thing it looks pure but it isnt. Pure substances - PowerPoint PPT Presentation

Solutes and Solvents

Solute and Solvent

Mixtures and Solutions1Heterogeneous materials - can see two partsMatterHomogeneous materials can see only one thing - one set of propertiesHomogeneous mixturesTheyre mixed together so well you only see one thing it looks pure but it isntPure substancesYou can only see one thing because there is only one kind of particle in it.Mechanical MixtureSolutionReview SolutionsAre solutions homogeneous or heterogeneous?HomogeneousAre solutions mixtures or pure substances?MixturesWhat kind of states can a solution be?Solid, liquid, or gasWhat are the two s words that every solution must have?A solute and a solvent3In a salt water solutionIs salt the solute or the solvent?SoluteIs water the solute or the solvent?SolventWhat does the solute do?Gets dissolvedWhat does the solvent do?Does the dissolving4

Solute (salt)Solvent (water)A Salt Water Solution5Factors Affecting How Fast a Solute Dissolves Temperature

Stirring or Shaking

Crushing (Surface Area)

Pressure

61. Temperature If we heat particles they will move fasterThe solvent will carry the solute particles away faster

7SoHotter = Dissolve Faster

82. Stirring or Shaking Stirring or shaking a solution moves the solute particles around so that they are closer to water particles

the water particles can then attract them easily and carry them away!

9SoStir or Shake = Dissolve Faster

103. Crushing (Surface Area) When a sugar cube is broken into small pieces, the individual sugar particles can get closer to water particles

the water particles can then attract them easily and carry them away!

11 Dissolving happens on the surface of particles

When solute is broken up, there is more surface area where dissolving can occurbroken up124. Pressure Pressure forces gas particles into the spaces between the liquid particlesPressure is used to dissolve carbon dioxide gas in liquid pop

gas13SoMore pressure = Dissolve Faster

14 Exteme Example of Pressure
