1. Acid-Base Behavior A Tutorial Review CHM 1020/Sinex Click on the text box to type your name in it. To advance slides, use the buttons.

2. Electrolyte behavior undissociatedions from dissociation abc Which box illustrates a non-electrolyte? Which box illustrates a strong electrolyte? Which box illustrates a weak electrolyte?

3. Acid-base behavior Let’s consider acids where HA dissociates into H + and A -. HAH+H+ A-A- HCl (g)H + (aq) + Cl - (aq) H2OH2O So in this example based on electrolyte behavior, HCl would be considered a acid.

4. abc Let’s consider acids where HA dissociates into H + and A -. HAH+H+ A-A- Acid-base behavior 2 So which box illustrates a weak acid with a partial dissociation?

5. Acid-base behavior 3 Rank the following weak acids from weakest (1) to strongest (3) HAH+H+ A-A- Rank them from lowest (1) to highest (3) pH

6. BH2OH2OBH + OH - Acid-base behavior 4 Now let’s consider the behavior of a weak base ab Which box contains the weaker base? Which box the highest pH?

7. Acid-base behavior 5 Most acid dissociation reactions are endothermic. HAH+H+ A-A- So which box illustrates the weak acid at the lowest temperature? abc

8. Acid-base behavior 6 The degree of dissociation influences the conductivity of the solution. HAH+H+ A-A- So which box illustrates the most conductive solution? abc

9. HAH+H+ A-A- Acid-base behavior 7 What happens if you add strong acid or strong base to the weak acid? Add strong acidAdd strong base

10. What happened when strong acid was added?

11. What happened when strong base was added?
