Complexometric titration Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.An indicator capable of producing an unambiguous color change is usually used to detect the end-point of the titration.DTA forms an octahedral complex with most 2+ metal cations, M 2+ , in aqueous solution. The main reason that EDTA is used so extensively in the standardization of metal cation solutions is that the formation constant for most metal cation-EDTA complexes is very high, meaning that the equilibrium for the reaction:

- Usually, an indicator is used in titration to determine the endpoint of the reaction. Once the endpoint volume is found, mathematics can be used to determine the concentration of the unknown. This procedure is commonly used in the field of analytical chemistry.

- Since EDTA forms complexes with many metal ions, this particular method can only be used in the absence of such ions as Ca 2+ , Ni 2+ , etc. The reaction of complexation is: Cu 2+(aq) + (EDTA) 2–(aq) → Cu(EDTA) 2–(aq) + 2H +(aq) The stoichiometry is one metal cation to one EDTA anion.he indicator used for the titration is called murexide. This indicator is highly colored and will complex with the copper ion to give a different colored species. During the titration, the EDTA 2– forms a more stable complex and frees the indicator, which then displays its original color.

Acidâbase titration An acid–base titration is the determination of the concentration of an acid or base by exactly neutralizing the acid or base with an acid or base of known concentration. This allows for quantitative analysis of the concentration of an unknown acid or base solution. It makes use of the neutralization reaction that occurs between acids and bases.

What is a Titration A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the known solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.

Titration Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand to determine concentration. The volume of titrant reacted is called titration volume.
