1. Q2 Four unknown substances have these pHs. A = pH 3
B = pH 10
C = pH D = pH 6
Identify each as a weak or strong acid or base.
Arrange them from the strongest acid to the strongest base.
Where in this list would water go?
Why?
4. What are 3 real-life uses of pH?

3. Today’s Objective: I understand Acid-Base Neutralization Reactions and Redox Reactions.

4. Remembering yesterday…
Which of these flasks
contains a base with
phenolphthalein?

6. Proton donor H+
Proton acceptor
OH-
H3O
H2O

7. Hydronium Ion: When the H+ ion attaches to a water molecule making it H3O

8. Litmus Paper: Indicator of whether a substance is acidic or basic.
Indicator Paper: Gives rough idea of amount of acidity or alkalinity of substance

11. When an acid & base react to form water and a salt
Acid-Base Reactions
Neutralization
pH of acid + pH of base = 7
When an acid & base react to form water and a salt

12. Product of Acid-Base Reaction is a Salt
Salts: ionic compounds created in an Acid-Base Reaction
Examples: NaCl
KCl
CuSO4

13. Zn + 2HCl  H2 + ZnCl2
Metal + Acid  H(g) + salt

14. Which is More Dangerous
...Acid or Base?

15. 2Al(s) + 3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s)
Remembering When…
Al(s) → Al3+(aq) + 3e–
Cu2+(aq) + 2e– → Cu(s)
2Al(s) + 3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s)

16. Redox: Oxidation Reduction Reaction
A reaction that occurs when electrons are transferred between ions

17. Copper Caper
