Titrimetry Analysis
Definition
- Quantitative analytical technique
- Uses a solution of accurately known concentration
- Measures the volume required to react with the analyte
Main purposes
- Determine analyte concentration
- Determine pH of the resulting solution
Important terms
- Titrant: solution of known concentration
- Analyte: substance being measured
Types of Acid and Base
Strong acid/base
- Completely dissociates
- Strong acid example: HCl
- Strong base example: Ba(OH)₂
Weak acid/base
- Partially dissociates
- Weak acid example: CH₃COOH
- Weak base example: NH₃
Acid-base theory
Lewis
- Acid → accepts electron pair
- Base → donates electron pair
Arrhenius
- Acid → produces H+ in water
- Base → produces OH- in water
- Examples: HCl, NaOH
Brønsted-Lowry
- Acid → proton donor
- Base → proton acceptor
Conjugate acid-base pairs
