Mixtures & Solutions
Term | Definition |
---|---|
Mixture | A combination of two or more substances in which no new kinds of matter are formed. |
Solution | A special mixture formed when one substances dissolves into another. |
Concentration | The amount of solute compared to the solvent (water); A measurement of the amount of solute that is dissolved in a solvent. |
Heterogeneous mixture | Mixtures that have uneven/different distribution of their parts and are physically separated; The parts are easily seen and can be easily separated. |
Homogeneous mixture | Mixtures whose parts are evenly distributed (solution); The separate parts come together and look the same. |
Solute | The substance in a solution that becomes dissolved and spreads out evenly. |
Solvent | The substance in a solution that dissolves the solute; Water the universal substance. |
Dissolve | When a substance breaks apart and spreads out even into a solution. |
Rate | How quickly or slowly something happens. |
Evaporation | Method of separating mixtures that uses boiling; Most solutions are separated using this method. |
Filters | Materials with very tiny holes that block solid or large particles, but allow gas, liquids, or small grains to pass through. |
Ways to Increase the Rate of Dissolving | Warm temperatures, stirring, and using small sized particles that have larger surface areas speed up the dissolving process. |
