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, HNO 3, HNO 2 H 2 SO 4, H 2 SO 3, H 2 CO 3 H 3 PO 4 H 3 PO 3

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 NH 3(aq) + H 2 O (l)  NH 4 + (aq) + OH - (aq) NH 3(aq) + H 2 O (l)  NH 4 + (aq) + OH - (aq) base acid base acid H 2 O (l)  H 3 O + (aq) + Cl - (aq) HCl (g) + H 2 O (l)  H 3 O + (aq) + Cl - (aq) Conjugate base Conjugate acid

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 – H 2 SO 4 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 H 2 O amphoteric? indicators how do we know strength? difference between strength and concentration what does pH stand for?

8. L earned H 2 O is amphoteric H 2 O is amphoteric

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

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

11. W ant to know 3 definitions of acids? what are pH of acids? uses of acids Why is H 2 O amphoteric? indicators how do we know strength? difference between strength and concentration what does pH stand for?  CHECK  CHECK video  CHECK scale and formulas  CHECK concentration and molarity  CHECK potential hydrogen but really is just a way to show the relative concentration of hydrogen ions
