Titration Curve, Endpoint and Equivalence Point
To understand acid-base titrations we need to learn about titration curves, endpoints, and equivalence points. These terms are explained below in detail.
Titration Curve
A titration curve is a graphical representation of a titration analysis, typically showing pH against the volume of titrant added. It helps identify the endpoint and equivalence point more precisely than using indicators. Different properties like pH, absorptivity, temperature, conductivity, or electrical current can reveal the endpoint of a reaction.
Endpoint
The endpoint of a titration is the stage where a color change or intensity shift indicates the completion of the reaction. It signifies the point at which the reactants have reacted completely. Indicators are often used to signal the endpoint of a titration visually.
Equivalence Point
The equivalence point is when chemically equivalent quantities of analyte and titrant exist in the system. At this point, moles of both species are equal, indicating that enough titrant has been combined with the analyte to neutralize it. It differs from the endpoint as it represents the exact stoichiometric point in the reaction.
Acid Base Titration
Acid Base titration is a fundamental method in the quantitative chemical analysis used to determine the concentration of acids or bases in a solution. This process involves the controlled addition of a known concentration of an acid or base (titrant) to a solution of the substance being analyzed until the reaction reaches a neutral point. The moles of acid and base are equal at this equivalence point, resulting in a neutral solution. A pH indicator is often used to monitor the progress of the reaction, and a titration curve can be constructed to visualize the pH changes throughout the titration process.
