Day 1 - Notes
Unit: Acids, Bases, and Solutions
Acids and Bases: Review of naming and Characteristics

2. After today you will be able to…
Define an acid and base according to the Arrhenius definition
Review the correct way to write the names and formulas for acids and bases
Describe and list properties that pertain to acids and bases

3. There are three different types of definitions for acids and bases, but for our purposes we will only work with one: Arrhenius.

4. Acids
An Arrhenius acid is an ionic compound that has the H+ ion as its cation.
Acids have a sour taste
(Ex: citric acid)
Acids will cause indicators to change colors

5. Indicators: Are substances that change color based on pH.

6. Acids Turn litmus paper pink or red The pH of acids is less than 7
Acids will react with metals in a single replacement reaction called corrosion.
Acids will react with bases in a double replacement reaction called neutralization.

7. Bases
An Arrhenius base is an ionic compound that has the OH- ion as its anion.
Bases have a bitter taste
Bases are slippery (Ex: soap)
Bases will cause indicators to change colors

8. Bases Bases change litmus paper blue.
The pH of bases is greater than 7.
Bases will react with acids (neutralization)

9. Review: Naming and Formula Writing for Bases
Use typical rules for naming ionic compounds:
NaOH ___________________
Mg(OH)2 ___________________
Aluminum Hydroxide ________
Sodium hydroxide
Magnesium hydroxide
Al(OH)3
Al (OH)-1

10. Review: Naming and Formula Writing for Acids
If the anion ends in…
“ide” then, ___________________
“ate” then, ___________________
“ite” then, ____________________
hydro____ic acid
____ic acid
____ous acid

11. Review: Naming and Formula Writing for Acids
For acids, look at the anion ending!
H3PO3 ___________________
HBr ___________________
Carbonic acid ______________
Remember H+1 is always the cation for acids!
“phosphite”
Phosphorous acid
“bromide”
Hydrobromic acid
“ic” must have been “ate”
H2CO3
H (CO3)-2
