  1. Solutions Integrated Science

  2. Solutions • Solutions are a type of Homogeneous Mixture • The whole solution looks the same. • You can’t see any of the individual parts.

  3. Solutions • Solutions have two parts • Solute • The substance that is dissolved • Solvent • The substance that dissolves the solute. + =

  4. Solutions • In homogeneous mixtures all of the parts are the same state of matter. • This means that AFTER you make the solution you only have one state of matter.

  5. Pick the Solute and Solvent • Salt Water • Solute = salt • Solvent = water • Kool Aid • Solute = Kool Aid or Sugar • Solvent = water • Tomato Soup • Solute = tomato • Solvent = water • Salad • Solute = tomato? • Solvent = lettuce

  6. Solutions • Solutions are classified by the amount of solute in the solvent • Unsaturated • When more solute can be dissolved in the solvent. • Saturated • When no more solute can be dissolved in the solvent. • Super Saturated • When the solvent is heated to have solute dissolved in it.

  7. Why do we put salt on icy sidewalks • Salt lowers the melting point so the ice melts. Pure water freezes at 0°C salt water freezes below 0…-5°C That means that if it is warmer than -5° the ice will melt.

  8. Why do we put salt in water • Salt raises the boiling point so the water is hotter and it cooks the pasta faster. Pure water boils at 100°C salt water boils above 100…105°C That means that the water is hotter when it boils so the pasta cooks faster.
