Study Notes
Analytical Chemistry
- Analytical chemistry is a measurement science, focusing on separating, identifying, and determining chemical substances.
- Classification of analytical chemistry includes:
- Quantitative analysis: determining the chemical identity of elements and compounds.
- Qualitative analysis: determining the relative amounts of each substance in a sample.
Lewis Acid-Base Theory
- Acids: Electron acceptors
- Bases: Electron donors
- A Lewis base is a substance containing an atom with unshared electron pairs (either -ve ions or molecules).
- A Lewis acid is a substance that accepts an electron pair (either +ve ions or molecules).
- Acid-base reactions form adducts (coordinate covalent bonds)
Brønsted-Lowry Acid-Base Theory
- Acids: Proton donors
- Bases: Proton acceptors
- An acid reaction with a base results in a conjugate acid and a conjugate base.
