- Acids and Bases
- Definitions
- Acid= Proton donor
- Base= Proton acceptor
- Acid base reaction= involves the transfer of a proton
- Monoprotic acid= Acid that releases one proton per molecule
- Diprotic= Acid that releases 2 protons per molecule
- Strong Acids
- All molecules dissociate into ions
- HCl, HNO3, H2SO4
- Weak Acids
- Only a small fraction of the molecules dissociate to form ions
- Organic acids
- Strong Acid = pH= -log(H+)
- Strong Base= Kw= (H+)(OH-)
- Weak Acid
- By itself Ka= (H+)2 / HY
- In buffer= (H+)(a-) / (HA)
