Ioding when combined in a compound is usually combined as the iodide. Iodide ions are negatively charged (ie each ion has an extra electron compared with an iodine atom). When elemental iodine is liberated, iodine atoms are formed from these ions which in turn pair up to form iodine molecules. When an Iodine ion changes into an atom it must lose the extra electron. From the acronym 'OILRIG' (Oxidation Is Loss of electrons, Reduction Is Gain of electrons) it is clear that as the elemental iodine has formed because of the loss of an electron the process must involve oxidation.

How is iodine librated in iodometric titration?
In an iodometric titration, iodine is liberated by the reaction between the analyte (substance being tested) and iodine solution. This reaction typically involves the reduction of a substance that releases iodine, which can then be titrated with a solution containing a reducing agent to determine the analyte concentration.
Why analysis of Cu from brass solution is considered as an iodometric titration?
Copper in brass can be oxidized to Cu2+ by iodine in a redox reaction. The iodine acts as the titrant in the reaction and the copper is being titrated. It is considered an iodometric titration due to the involvement of iodine in the titration process.
What is the change of oxidation number of sulphur during iodometric titration experiment?
In an iodometric titration experiment, the oxidation number of sulfur changes from -2 in the thiosulfate ion (S2O32-) to +4 in the sulfate ion (SO42-) as sulfur gains oxygen atoms. This change indicates the transfer of electrons and oxidation of sulfur during the reaction.
What are iodometric and iodometric titration?
Iodometric titration involves determining the concentration of a substance by measuring the amount of iodine generated in a reaction. Iodometric titration, on the other hand, refers to a type of redox titration that uses iodine as the titrant to determine the amount of a substance, typically an oxidizing agent, present in a sample.
What is iodometry and iodimetry titration?
Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.

Why you do not use H2SO4 in iodometric titration?
Using H2SO4 in iodometric titration can lead to the formation of H2O2, which interferes with the reaction. It can also oxidize iodide ions prematurely, affecting the accuracy of the titration. Therefore, a different acid like HCl is typically used in iodometric titration.
Does the amount of potassium iodide added to the potassium iodate solution affect the amounts of iodine liberated in iodometric titration?
Yes, the amount of potassium iodide added to the potassium iodate solution in iodometric titration affects the amount of iodine liberated. Potassium iodide serves as a reducing agent, reacting with the iodate ion to form iodine. The quantity of potassium iodide added determines the rate and completeness of this reaction, impacting the amount of liberated iodine available for titration.
What is the difference between iodometric titration and iodimetric titration?
Iodometric titration involves the titration of iodine with a reducing agent, while iodimetric titration involves the titration of iodide with an oxidizing agent. In iodometric titration, iodine is detected by a starch indicator to determine the end point, while in iodimetric titration, iodide ion concentration is determined by titration with a standard solution of an oxidizing agent.
Is iodometric titration and redox titration is same?
No, they are not the same, but 1 is part of 2.Iodometric titration is just one of the (larger) group (or class) of oxidimetric titrations, which in turn is part of the much (larger) group (or class) of volumetric analysis method.
Can we carry out an iodometric titration using a potentiometer?
No, iodometric titration is typically done using a standard titration setup with a burette and indicator to detect the endpoint. A potentiometer measures the voltage produced in a system, making it unsuitable for this type of titration.
Why the oxidation reduction titration must be in basic medium?
It is not mandatory; acids are also titrated.
What is iodometric titration?
In this titration iodine is liberated ....Added:... from (excess of) iodide by an oxidant. The Iodine is then titrated with thio (di-sodium thio-sulfate) and starch as indicator added just before the expected equivalence point.
