Unit 2: Acids and Bases Flashcards
1
Q
What are the general properties of acids?
A
- Sour
- Blue litmus turns red
- Produces CO2 with carbonates
- Dissolves many metals releasing Hydrogen
- pH <7
2
Q
What are the general properties of bases?
A
- Bitter taste
- Red litmus turns blue
- Soapy feeling
- Neutralize acids
- Ph >7
3
Q
What is the Bronsted-Lowry theory?
A
- Acid is a proton donor and bases are proton acceptors
- You can identify acids on each side by which contains more Hydrogen atoms
4

A
- HClO4 (perchloric acid)
- HCl (hydrochloric acid)
- HBr (hydrobromic acid)
- HI (hydroiodic acid)
- HNO3 (nitric acid)
- H2SO4 (sulfuric acid)
