2. Section 7.1 Naming and Writing Formulas for Acids and Bases
Acids are…
Compounds that give off hydrogen ions (H1+) when dissolved in water
Will start the formula with H.
There will always be some Hydrogen next to an anion.
The anion determines the name.

3. F. Rules for Naming acids:
(anions with different suffix: -ide, -ite, -ate)
1. If anion attached to hydrogen ends in -ide, put prefix hydro- and change -ide to -ic acid
HCl - hydrogen ion and chloride ion = hydrochloric acid
H2S hydrogen ion and sulfide ion = hydrosulfuric acid

4. F. Rules for Naming acids:
* If the anion has oxygen in it, then it ends in -ate or –ite (polyatomic)
change the suffix -ate to -ic acid (use no prefix)
Example: HNO3 Hydrogen and nitrate ions = Nitric acid
change the suffix -ite to -ous acid (use no prefix)
Example: HNO2 Hydrogen and nitrite ions = Nitrous acid

5. F. Rules for Naming Acid hydro-___-ic acid ____-ide _____-ic acid
Normal ending
____-ide
____-ate
____-ite
Acid name is…
hydro-___-ic acid
_____-ic acid
_____-ous acid

6. Practice by naming these:HF
H2S
H2SO3
H2SO4
HCN
hydrofluoric acid
hydrosulfuric acid
sulfurous acid
sulfuric acid
hydrocyanic acid

7. Write formulas for these:
hydroiodic acid
carbonic acid
phosphorous acid
hydrobromic acid
acetic acid HI
H2CO3
H3PO3
HBr
CH3COOH
* breaks the rule of starting with H

8. Names and Formulas for Bases
Base - an ionic compound that produces hydroxide ions (OH1-) when dissolved in water
Bases are named the same way as other ionic compounds:
The name of the cation (which is a metal) is followed by the name of the anion (which will be hydroxide).

9. G. Names and Formulas for Bases
To write the formula:
Write the symbol for the metal cation
followed by the formula for the hydroxide ion (OH1-)
then use the criss-cross method to balance the charges.
NaOH is sodium hydroxide
Ca(OH)2 is calcium hydroxide

10. Practice by writing the formula for the following:
Magnesium hydroxide
Iron (III) hydroxide
Zinc hydroxide
Mg(OH)2
Fe(OH)3
Zn(OH)2
