Transcript

  • 1.  
  • 2. WHAT ARE ACIDS?
    • Acids produce hydrogen ions in water.
    • Example of an acid (HA) in solution
    A - H + H + A - A - H + H + A -
  • 3. WHAT ARE BASES?
    • They are metal oxides or metal hydroxides .
    • Examples:
      • Sodium hydroxide (NaOH)
      • Copper (II) oxide (CuO)
    Copper (II) Oxide NaOH Can you name some other examples of bases?
  • 4. SOLUBLE BASES
    • Soluble bases are called alkalis
    • Alkali dissolves in water to produce hydroxide (OH - ) ions
    • Example:
      • NaOH
    Na + OH - Na + OH - Na + OH - Na + OH -
  • 5. WHAT HAPPENS WHEN ACID REACTS WITH A BASE?
    • Let us visualize the changes that takes place on the molecular level!

  • 6. ACID AND BASE REACTION
    • The reaction between an acid and a base is called neutralisation.
    • Example 1:
      • Sodium hydroxide + hydrochloric acid  Sodium chloride + water
    Now, let’s write the chemical equation! NaOH + HCl  NaCl + H 2 O
  • 7. ACID AND BASE REACTION
    • Example 2
    • Copper (II) oxide + sulfuric acid  copper(II) sulfate + water
    Now, let’s write the chemical equation! CuO + H 2 SO 4  CuSO 4 + H 2 O
  • 8. SUMMARY: NEUTRALISATION REACTION
    • Acid + Base  Salt + water
    • Ionic Equation:
      • H + (aq) + OH - (aq)  H 2 O (l)
  • 9. CAN YOU ALSO… DRAW YOUR OWN CONCEPT MAP!?!
    • Group leaders:
    • Create a mindmap on mindmeister
    • Invite your group mates
    • All members of the group:
    • Contribute to the concept map
    • Post the finalized copy of concept map onto your pbwiki group
  • 10. THE END…
