Acids and Bases

Acids and Bases

1. An acid is a substances that will donate a proton (H+) to a base

2. A base is a substance that will accept a proton from an acid

3. Conjugate acid-base pairings

   • HCl(g) + H2O(l) <--> H3O+(aq) + Cl-(aq)
     • A1 B2 A2 B1

4. Water is amphoteric so it behaves as an acid with a base and as a base with an acid

5. Equations

   • Acid + Metal -> Salt + Hydrogen
   • Acid +Alkali -> Salt + Water
   • Acid + Base (metal oxide) -> Salt + Water
   • Acid + Carbonate -> Salt + Water + Carbon Dioxide
   • Acid + Hydrogen Carbonate -> Salt + Water
   • (Carboxylic) Acid + Alcohol -> Ester + Water

6. A salt is an acid that has its hydrogen ions replaced with metal ions or ammonium ions
