About Titrations
Formula
pH = -log[H⁺] or pH = 14 - pOH
Where [H⁺] = hydrogen ion concentration, [OH⁻] = hydroxide ion concentration
Key Concepts
Titration: Process of determining concentration using a known reagent
Equivalence Point: Point where moles of acid = moles of base
Endpoint: Point where indicator changes color
Buffer Region: Region where pH changes slowly
pH Scale: 0-14 scale measuring acidity/basicity
pH Indicators
Methyl Orange: Red (pH < 3.1) to Yellow (pH > 4.4)
Methyl Red: Red (pH < 6.2) to Yellow (pH > 8.0)
Phenolphthalein: Colorless (pH < 8.3) to Pink (pH > 10.0)
Universal Indicator: Full pH range with multiple colors
