Titration analysis

Definition

Titration analysis is a quantitative chemical technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration.

5 Must Know Facts For Your Next Test

1. The point at which the reaction is complete in titration is called the equivalence point.
2. Indicators are often used in titration to signal the end point, where a noticeable change occurs, such as a color change.
3. A titrant is the solution of known concentration added from a burette during the titration process.
4. The volume of titrant added to reach the equivalence point helps calculate the unknown concentration using stoichiometric relationships.
5. $M_1V_1 = M_2V_2$ is a common formula used in dilution and titration calculations, where $M$ represents molarity and $V$ represents volume.
