What is Complexometric titration in chemistry?
What is Complexometric titration in chemistry?
complexometric titration. (kəmˌplɛksəʊˈmɛtrɪk) n. (Chemistry) chem a titration in which a coloured complex is formed, usually by the use of a chelating agent, such as EDTA, the end point being marked by a sharp decrease in the concentration of free metal ions.
What is incremental titration in chemistry?
Titration is the incremental addition of a known concentration solution (called a titrant) to a known volume of an unknown concentration solution before the reaction achieves neutralization, which is often signaled by a color shift. What is end point in titration?
What is complexometry in chemistry?
• Complexometry : is the type of volumetric analysis involving the formation of complexes which are slightly ionized in solution, like weak electrolyte and sparingly soluble salt.
What is meant by EDTA titration?
(Chemistry) chema titration in which a coloured complex is formed, usually by the use of a chelating agent, such as EDTA, the end point being marked by a sharp decrease in the concentration of free metal ions
2. • Complexometric titration is a form of volumetric titration in which the formation of a colored complex is used to indicate the end point of a titration. • The complexes are formed by the reaction of a metal ion ( an acceptor, a central atom or a cation) with an anion, a neutral molecule or very rarely a positive ion. 3.
Why do we use EDTA in complexometric titration?
Since they are characterised with less solubility in water, they are used for titration. Sometimes simple titration methods are used to determine the simple metal ions present in water. But to determine the exact number of metal ions present complexometric titration is used, and it is conducted using EDTA.
How can EDTA be used as chelating titrant?
EDTA can be used as chelating titrant (titrant can be defined as the solution whose concentration is known in the titration) in many ways. So, EDTA titrations can be performed in many ways. Few of them are given as follows – Direct Titration- It is the most convenient and simple method of complexometric titration using EDTA.
What is titrant volume in titration?
Titrant Volume is defined as the volume of a titrant that is reacted. Complexometric Titration is in the detection of mixtures of different metal ions present in the solution. When each drop of titrant is added, the reaction reaches an equilibrium state swiftly.
