Iodimetry is a titration method used to determine the concentration of oxidizing agents by measuring the amount of iodine they can convert from iodide ions. In this method, an iodide solution is titrated with an oxidizing agent, leading to the formation of iodine. The iodine is then titrated with a thiosulfate solution to determine the amount of oxidizing agent present.

What is iodimetry?

Iodimetry is a type of volumetric analysis that involves the use of iodine as a titrant to determine the concentration of an analyte (substance being analyzed) in a solution. It is commonly used in chemistry to determine the amount of substances such as ascorbic acid, thiosulfate, or hydrogen peroxide in a sample.


Difference between iodometry and iodimetry?

When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry". When an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".


What is the effect of adding sulfuric acid in iodimetry titration?

Adding sulfuric acid in iodimetry titration helps to oxidize iodide ions to iodine, which is then titrated with a standard solution of sodium thiosulfate. Sulfuric acid also prevents the interference of other reducing agents that may be present in the sample being tested.


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.

What is the use of Sodium thiosulphate in iodometry?

In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.
