Some common indicators used in redox titrations are potassium permanganate (KMnO4), which changes color from purple to colorless in acidic conditions, and potassium dichromate (K2Cr2O7), which changes from orange to green in acidic conditions. Other indicators include starch-iodine complex and ferroin.

What is redox titration?

Redox titration is a type of titration that involves a redox reaction between the analyte and titrant. In this titration, the endpoint is determined by monitoring the change in oxidation state of the analyte. It is commonly used to determine the concentration of oxidizing or reducing agents in a sample.


What are the four classes of titration?

The four classes of titration are acid-base titrations, redox titrations, complexometric titrations, and precipitation titrations. These classes are based on the type of reaction that occurs during the titration process and the corresponding indicators used to determine the endpoint.


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.


What is the theory of the redox titration?

Redox titration is a type of titration based on a redox reaction between the analyte and titrant. The theory behind redox titration is that the number of electrons transferred in the reaction is used to determine the amount of substance being analyzed. This is typically done by monitoring the change in concentration of a redox indicator or analyzing the endpoint using a potentiometric method.


How many types of indictors are used in titration?

There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.

How many tipes of titration?

There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.


Where redox titration is used?

Redox titration is commonly used in analytical chemistry to determine the concentration of oxidizing or reducing agents in a sample. It is also used in industries such as food and pharmaceuticals to ensure product quality and compliance with regulations. Additionally, redox titration is employed in environmental monitoring to assess levels of pollutants in air, water, and soil.


Why sulfuric acid is used in Redox titration instead of HNO3?

Sulfuric acid is commonly used in redox titrations because it is a strong acid and does not participate in the redox reactions. Nitric acid (HNO3) can act as an oxidizing agent itself, which can interfere with the redox titration process by introducing additional reactions.


What is difference between external and internal indicators used in titration?

Internal indicators that are used in titration exist in the titration reaction as either a reactant or a product. External indicators is added to the reaction mixture, but does not exist in the reaction.


What are the answers to the determination of iron by redox titration?

The answers to the determination of iron by redox titration are the concentration of the iron solution and the volume of the titrant needed to reach the endpoint of the titration.


Difference between acid base titration and redox titration?

In acid-base titration, the reaction involves the transfer of protons between the acid and base, with the endpoint usually determined by a pH indicator. Redox titration, on the other hand, involves the transfer of electrons between the oxidizing and reducing agents, with the endpoint typically determined by a change in color or potential. Acid-base titrations are used to determine the concentration of acids or bases, while redox titrations are to determine the concentration of oxidizing or reducing agents.


Why don't we use indicators in redox-titration?

Because the end point can easily be observed. Example: consider the titration between potassium manganate (IV) which is purple and ammonium iron (II) sulfate - colourless. At the end point the colourless standard solution will turn pale pink when the correct volume of deep purple titre is added. No indicator is required. Also this is not necessarily an acid base rxn
