Presentation Transcript

  1. Acids and BasesOGT

  2. Acid • Acids taste sour – think vinegar, lemons • Dissolve in water (H2O) • Are corrosive • Will conduct electricity

  3. Acid • When acids dissolve – they ionize • This ionizationmeans it yields hydrogen ions • This is a hydrogen ion H + HCl H + HNO3 H + CH3COOHH +

  4. Base • Bases taste bitter and have aslippery feel • Bases dissolve in water • Bases are corrosive • Bases conduct electricity

  5. Base • When bases dissolve they ionize • This ionizationmeans it yields hydroxide ions • This is a hydroxide ion OH - NaOHOH - NH4OH OH -

  6. pH • pH scalesare used to measure the concentration of H + ions This scale ranges from 0  14

  7. How do we measure it?

  8. 7 Below 7.0 Above 7.00

  9. The Neutralization Reaction • Acids - bases can cancel each other out • When they do - they are neutralized • A reaction like this is called a neutralization reactions

  10. Acids and Bases End
