Theory & Core Foundations
Titration is a fundamental analytical chemistry technique used to determine the unknown concentration of an identified analyte (a substance being analyzed). A reagent, termed the titrant, is prepared as a standard solution of known concentration and volume.
The titrant is reacted with a solution of analyte to determine the analyte's concentration. The volume of titrant reacted is called the titration volume. For acid-base titrations, a pH indicator (like phenolphthalein or methyl orange) is often used to detect the endpoint—the point at which the color changes, which closely approximates the equivalence point.
The equivalence point is the ideal point in the titration where the amount of titrant added is stoichiometrically equal to the amount of analyte present in the sample.
Mathematical Foundations
The core principle of titration is stoichiometry. At the equivalence point, the moles of acid equal the moles of base. For weak acids, the buffer region is governed by the Henderson-Hasselbalch equation.
How The Simulation Works
Select your reagents and parameters. Use the titration controls to slowly add titrant from the burette into the analyte flask. Watch the live pH curve update in real-time. Stop adding titrant as soon as you observe a permanent color change from the indicator.
