Presentation Transcript

  1. Acid and Base 5/13/11 warm-up What are the 3 definitions of Acid and base?

  2. Arrhenius definition acid- hydrogen containing compounds that ionize to yield H+ ions base – compounds that ionize to produce hydroxide or OH- ions list examples of each of these monoprotic – diprotic - triprotic - HCl, HBr, HI, HF, HNO3 ,HNO2 H2SO4, H2SO3, H2CO3 H3PO4 H3PO3

  3. Bronsted-Lowry def acid- hydrogen ion donor base – hydrogen ion acceptor conjugate acid-base pair conjugate acid – particle formed when base gains H+ conjugate base – particle formed when acid has donated (loses) H+

  4. Conjugate acid and base pairs • NH3(aq) + H2O(l) NH4+ (aq) + OH- (aq) base acid Conjugate acid Conjugate base HCl (g) + H2O(l) H3O+ (aq) + Cl- (aq)

  5. K now Write down in a list all the things you know about Acids and Bases. Quiz this Thursday Test Next Tuesday 5/24 on Acids and Bases. 2 labs this week. Titration and indicator lab Next up Gas Laws Test the next Thursday 5/26

  6. K now Corrosive H in the beginning how to name them sour taste gastric acid-stomach acid – HCl battery acid – H2SO4 aqueous solutions pH scale act as electrolytes

  7. W ant to know 3 definitions of acids? what are pH of acids? uses of acids Why is H2O amphoteric? indicators how do we know strength? difference between strength and concentration what does pH stand for?

  8. L earned • H2O is amphoteric

  9. Acid/Base • Warm up 5/16/2011 • Copy down pH scale and common substances from page 598 • Take out notes from Chapter 19

  10. Titration • What is a titration? See book p 615 • Vocab to know • equivalence point • end point • indicator • neutralization reaction • Let’s do practice problems 32, 33 on pg 616

  11. W ant to know  CHECK  CHECK scale and formulas 3 definitions of acids? what are pH of acids? uses of acids Why is H2O amphoteric? indicators how do we know strength? difference between strength and concentration what does pH stand for?  CHECK video  CHECK  CHECK • CHECK concentration and molarity • CHECK potential hydrogen but really is just a way to show the relative concentration of hydrogen ions
