Endpoint

Science / Chemistry / Endpoint: The experimental estimate of the equivalence point in a titration.

Titration Curve

Science / Chemistry / Titration Curve: A plot that summarizes data collected in a titration. A linear titration curve plots moles of analyte (or, some quantity proportional to moles of analyte) on the Y axis, and the volume of titrant adde MORE

Adsorption Indicator

Science / Chemistry / Adsorption Indicator: A substance that indicates an excess of a reactant in a precipitation reaction. For example, dichlorofluorescein is added to an NaCl solution being titrated with silver nitrate. Before the endpoint, e MORE

Organochromic Indicators

Science / Chemistry / Organochromic Indicators: Colored organic compounds that change color when they chelate different metals. Organochromic indicators are used to determine the endpoint in complexometric titrations. Examples of organochromic indi MORE

Complexometric Titration

Science / Chemistry / Complexometric Titration: A titration based on a reaction between a ligand and a metal ion to form a complex. For example, free Ca2+ in milk powder can be determined by titrating a milk powder sample with EDTA solution, which MORE
