Why is ammonium thiocyanate used in iodometry of copper?

Ammonium thiocyanate is used as an indicator in the iodometry of copper because it forms a red complex with copper ions. By adding ammonium thiocyanate to the copper solution, the color change from white to red indicates the end point of the titration, allowing for the determination of copper concentration.


What are the uses of iodometry?

Iodometry is used to determine the concentration of oxidizing agents by titrating them with a solution containing iodide ions. It is commonly used in analyzing chlorine in water treatment, measuring the concentration of hydrogen peroxide, and determining the ascorbic acid content in vitamin C tablets.


Why starch indicator is not added right from the beginning of titration in iodometry?

Starch indicator should not be added at the beginning of an iodometry titration because iodine can form a complex with the starch, resulting in a blue-black color that can obscure the endpoint. It is best to add the starch indicator near the endpoint, when the iodine is almost completely reacted, to help visualize the color change.


What do you mean by IODOMETRY?

IODOMETRY is a quantitative method that involves the determination of the concentration of an oxidizing agent through the use of iodine as a reducing agent. It is based on the reaction between iodine and the substance being analyzed in the presence of an indicator. The amount of iodine consumed or produced in the reaction is used to calculate the concentration of the analyte.


What is the role of copper sulphate in estimation of copper by iodometry?

Copper sulfate is used to keep the copper ions in solution so that they can be titrated accurately. Iodometry involves the use of iodine to oxidize copper ions to cupric ions, which are then titrated with a standardized solution of thiosulfate to determine the amount of copper present. Copper sulfate ensures the copper ions remain in solution throughout the titration process.

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 the iodemetry use for?

If you mean iodometry, it is the use of the chemical iodine in a process called titration. Titration is often used to determine the concentration of a chemical in a solution. A common use of iodometry was determination of salt concentration in salt water. It is not the most accurate or quickest way these days.

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.
