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 else can I help you with?
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.
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 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 function of potassium iodide in iodometric titration?
Potassium iodide is used in iodometric titration as a source of iodide ions. It reacts with iodine to form triiodide ions, which are then titrated with a standard solution of thiosulfate to determine the concentration of the oxidizing agent.
Why is it recommended to carryout iodometric titrations as quick as possible?
Iodometric titrations involve the titration of iodine with a reducing agent. Iodine is volatile and can escape into the air, which can lead to errors in the titration results. To minimize these errors, it is recommended to carry out iodometric titrations as quickly as possible to prevent the loss of iodine and ensure accurate results.
Why use sodium bicarbonate in iodometric titration?
Sodium bicarbonate is used in iodometric titration to react with excess iodine that may be present after the reaction with the analyte. This helps neutralize the solution and prevent any further reactions that could interfere with the titration endpoint. Additionally, sodium bicarbonate helps stabilize the pH of the solution during the titration process.
Why keep in dark in iodometric titration?
Keeping the solution in the dark during iodometric titration helps prevent any unwanted reactions due to exposure to light, which could interfere with the accuracy of the titration results. Light can induce photoreactions that can alter the chemical species being titrated, leading to incorrect readings. Therefore, maintaining the solution in the dark helps ensure the reliability and precision of the titration.
Why you use iodine in iodometric titration?
Iodine is used in iodometric titration as the titrant because it can easily react with reducing agents to form iodide ions. Its reaction with reducing agents leads to a change in color, making it useful for visual endpoint detection. This allows for the determination of the concentration of the reducing agent being analyzed in the titration process.
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.
What is hypo solution used in chemistry for iodometric titration?
Hypo solution, also known as sodium thiosulfate solution, is commonly used in chemistry for iodometric titrations as a titrant to react with excess iodine after the reaction with the analyte. It is used to neutralize the excess iodine to determine the amount of analyte present in the sample.
