2. Now read
Read the pages and fill in the After side write true or false for each statement.

3. What are some characteristics of acids and bases?
pH < 7
pH > 7
Change the color of acid-base indicators.
Bitter Taste
Sour Taste
Produce
H+ ion
Produce
OH- ion
Acids
Bases
React with each other to form salt and water
Turns Red
Litmus paper
BLUE
Turns Blue
Litmus paper
RED
React with active metals to form H2 gas.
Feel slippery
Electrolytes
Called Alkalines

5. Rules for naming Binary Acids (H+nonmetal)
Start with HYDRO~
Write the ROOT of the NONMETAL
Change the ending to ~IC
Add the word ACID
Example: H2S  hydrosulfuric acid

6. You try ….
HF  HCl  HBr 
Hydroflouric acid Hydrochloric acid Hydrobromic acid

7. Rules for naming Ternary Acids (H+polyatomic)
NO HYDRO!!!!!!!!!!
Name the POLYATOMIC ION
Change the ending;
ate  IC
ite OUS
Add ACID
Examples H2SO4  sulfuric acid
H2SO3  sulfurous acid

8. You try …. Nitric acid Nitrous acid Carbonic acid
HNO3  HNO₂  H₂CO3 

9. Formulas of Acids
Step 1-- The cation will be hydrogen. Write H first +1 charge.
Step 2-- Identify the anion and its charge (nonmetal or polyatomic)
Step 3 --Balance the charges (Use criss-cross method)

10. Formulas of Acids
Hydrofluoric Acid: H +1 F -1 H F 1 1 HF

11. Formulas of Acids
Carbonic Acid:
(CO3) H
(CO3) -2 H +1 1 2
H2CO3

12. Names of Bases
Bases are compounds that produce hydroxide ions when dissolved in water.
We refer to them as-ALKALINE
Ionic compounds that are bases are named like ionic compounds

13. Name the anion (hydroxide) Base Examples NaOH: Sodium Hydroxide
Naming Bases
Name cation (metal)
Name the anion (hydroxide)
Base Examples
NaOH: Sodium Hydroxide
LiOH: Lithium Hydroxide
KOH: Potassium Hydroxide
Ca(OH)2 : Calcium hydroxide

14. Formulas of Bases
Lithium Hydroxide: Li +1
(OH) -1 Li
(OH) 1 1
LiOH

15. (OH) Fe (OH) Fe Fe(OH)2 Formulas of Bases Iron (II) Hydroxide: +2 -1 2

17. Name Each Acid or Base A. HF:____________________
B. HNO3 :_________________
C. KOH :__________________
D. H2 SO4 :_________________
E. HMnO4:________________
F. H3PO4:_________________
G. H2S:____________________

18. Write the formula: chromic acid :_________________
iron (II) hydroxide:_____________
hydriodic acid:_________________
lithium hydroxide:_______________
hydrobromic acid:_______________
nitrous acid:___________________
sodium hydroxide:_______________

19. BRA: Blue → Red = Acid Properties of Acids Acids start with hydrogen
Acids turn litmus
Blue litmus paper turns red.
BRA: Blue → Red = Acid

20. Properties of Acids Acids taste sour
Acids react with bases to produce salt and water.
This is a neutralization reaction
5) Acids conduct electricity

21. Properties of Acids Acids react with bases to produce salt and water.
This is a neutralization reaction
Acids conduct electricity
Acids form H+ ions in water

22. Properties of Bases Bases feel slippery Bases end with hydroxide (-OH)
Turn litmus red  blue
RBB: red  blue = base
Bases feel slippery

23. Properties of Bases
Bases react with acid to form salt and water. This is called neutralization reaction.
Bases conduct electricity
Bases form –OH ions in water

24. Bronstead Theory
Conjugates

25. Properties of acids and bases- showing this one today or tomorrow
Properties of acids and bases- showing this one today or tomorrow. Great tie in from last unit. 3 min long
Music video…cute!! That same guy from Sat. training
Nuetralization reaction. Great realistic tie in. Use of bases to neutralize stomach acids
