Solutions and suspensions i

  1. 1. Solutions and Suspensions
  2. 2. Solutions and Suspensions <ul><li>Objectives: </li></ul><ul><li>Recognise the differences between solutes, solvents and solutions. </li></ul><ul><li>Understand the characteristics of a solution. </li></ul><ul><li>Create an awareness of the applications of solutions in our daily lives. </li></ul><ul><li>Understand the various attributes of suspensions. </li></ul><ul><li>State examples of suspensions in our daily lives. </li></ul>
  3. 3. Solutions and Suspensions <ul><li>What are solutions and suspensions? </li></ul><ul><li>Solutions and suspensions are mixtures . </li></ul><ul><li>They have different properties . </li></ul>
  4. 4. Solutions and Suspensions <ul><li>How to form solutions? </li></ul><ul><li>Sugar solution - Dissolve sugar in water </li></ul>SOLUTE SOLVENT
  5. 5. Solutions and Suspensions <ul><li>SOLUTE – substance that dissolves in solvent </li></ul><ul><li>SOLVENT – substance the dissolves the solute </li></ul>Brass zinc tin Soda water water carbon dioxide Sugar water Water sugar SOLUTION SOLVENT SOLUTE
  6. 6. Solutions and Suspensions SOLUTIONS
  7. 7. Solutions and Suspensions <ul><li>Solutions are formed when: </li></ul><ul><li>(1) Mixture is homogeneous. Same colour, density, properties throughout liquid. </li></ul><ul><li>(2) Solute does not separate from solvent by itself </li></ul><ul><li>(3) Solution passes through filter paper completely </li></ul>
  8. 8. Solutions and Suspensions Filtration Technique Solutions passes through filter paper because solutes are smaller than 0.00000000001m!
  9. 9. Solutions and Suspensions <ul><li>How to form Suspensions? </li></ul><ul><li>Muddy water – mud mixed in water </li></ul>
  10. 10. Solutions and Suspensions <ul><li>Suspensions are formed when the particles are bigger than 0.000001m </li></ul><ul><li>These particles can be seen with the eye. </li></ul>Oil droplets in air Dust in air Mud in water TYPES OF SUSPENSIONS
  11. 11. Solutions and Suspensions <ul><li>Suspensions are formed when: </li></ul><ul><li>(1) Mixture is non-homogeneous. Different colour density, properties throughout liquid. </li></ul><ul><li>(2) Solute separates from solvent by itself </li></ul><ul><li>(3) Insoluble particles left on filter paper after filtration. </li></ul>
  12. 12. Solutions and Suspension Residue remains behind in filter paper Liquid passes through filter paper
  13. 13. Solutions and Suspensions Both are mixtures Similarities Non-Homogeneous Homogeneous Residue after filtration No residue after filtration Solute does not separate by itself from solvent Solute separates by itself in solvent Suspension Solutions Differences
