Properties of Solutions

  1. 1. Solutions and Suspensions
  2. 2. <ul><li>Solutions are mixtures in which soluble particles are completely dissolved in a liquid or gas. </li></ul>What are Solutions?
  3. 3. How do we create a solution? <ul><li>Solute + Solvent = Solution </li></ul><ul><li>Example: salt + water  salt solution </li></ul><ul><li>(solute) (solvent) </li></ul>The solid which fully dissolves The liquid which is used to dissolve the solid
  4. 4. Properties of Solutions <ul><li>Homogeneous (solvent & solute particles evenly spread throughout the solvent) </li></ul><ul><li>No residue (undissolved solid) is left after </li></ul><ul><li>filtration </li></ul>
  5. 5. Properties of Solutions <ul><li>No separation of </li></ul><ul><li>solute and solvent </li></ul><ul><li>when left to stand </li></ul><ul><li>Light is able to completely pass through a solution </li></ul>
  6. 6. Dissolving solid to form a solution <ul><li>When a solid dissolves to form a solution, the solute particles separate and mix evenly with the solvent particles. </li></ul>
  7. 7. Uses of solutions in Homes <ul><li>Soap and detergent are dissolved in water to help us wash our laundry. </li></ul><ul><li>Syrups are dissolved in the water to make drinks. </li></ul><ul><li>Salt, sugar and other condiments are dissolved in liquids when we cook. </li></ul>
  8. 8. Uses of solutions in Industries <ul><li>Dyes are dissolved in water to produce colourful fabrics. </li></ul><ul><li>Oils from plants and flowers are dissolved in alcohol to produce perfumes. </li></ul>
  9. 9. Types of solutions State of solute State of solvent Examples of solution solid solid <ul><li>Alloys </li></ul><ul><li>Bronze (tin dissolved in copper) </li></ul><ul><li>Steel (iron, carbon + others) </li></ul><ul><li>Brass (zinc dissolved in copper) </li></ul>gas gas Air (oxygen, carbon dioxide, noble gases dissolve in nitrogen)
  10. 10. Types of solutions State of solute State of solvent Examples of solution Solid Liquid <ul><li>Amalgam </li></ul><ul><li>( silver, tin, gold or copper dissolves in mercury) </li></ul><ul><li>Sugar solution </li></ul><ul><li>(sugar dissolves in water) </li></ul>Liquid Alcoholic drinks (alcohol dissolves in water) Gas Aerated (Gas dissolved in water)
