PRESENTATION OUTLINE
Unit 11
Acids and Bases
Acids Properties!
- Taste Sour.
- have a pH
- will react with some metals & make hydrogen gas.
- Turn litmus paper blue.
- have more H+ ions than OH- ions
- when combined with a base will produce water and a salt.
Base Properties!
- Taste Bitter
- have a pH > 7
- feel slippery
- turn litmus paper red
- have fewer H+ ions than OH- ions
- when combined with an acid will produce water and salt.
Both Acids and Bases!
- Are Electrolytes
- will conduct electricity
- can change colors of indicators.
Arrhenius Acids and Bases!
Acids were defined as proton donors and bases as proton acceptors
Bronsted-Lowry Acids and Bases
Defines acids and bases as conjugate pairs that differ by one proton.
pOH and pH!
The formulas will help you find H+, OH-, pOH & pH.
pOH & pH formulas
- [H+] = 10-pH
- pH = -log[H+]
- pOH = -log[OH−]
- [OH−] = 10-pOH
- pH + pOH = 14
- [H+][OH−]=1 x 10-14
