📖 About This Experiment

Titration is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte. A reagent, called the titrant, is prepared as a standard solution of known concentration and volume. The titrant reacts with the analyte to determine its concentration.

💡 Key Concepts

  • •Titrant: Solution of known concentration in the burette
  • •Analyte: Solution of unknown concentration in the flask
  • •Equivalence Point: When moles of titrant equal moles of analyte
  • •Endpoint: Point where indicator changes color
  • •Indicator: Substance that changes color at specific pH

🔢 Key Formulas

Titration Formula
M₁V₁ = M₂V₂
Where M = molarity, V = volume
For Acid-Base Titration
MₐVₐ = M_bV_b × (nₐ/n_b)
Where n = moles of H⁺ or OH⁻
pH Calculation
pH = -log₁₀[H⁺]
