Why is no indicator needed in redox titration experiment?
No indicator is needed in redox titration because the endpoint of the titration is determined by a change in the appearance of the titrand. This change can be detected visually, such as a color change, indicating the completion of the reaction without the need for an indicator.
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.
What is the function of starch solution in the redox titration?
Starch solution is used as an indicator in redox titrations to detect the endpoint of the titration. It forms a complex with triiodide ions to produce a blue-black color when excess iodine is present, indicating that the reaction has reached completion. This helps in determining the equivalence point of the titration.
What is the use of ferroin indicator in redox titration of Mohr's salt?
Ferroin indicator is used in the redox titration of Mohr's salt as it changes color when the Fe2+ ions are completely oxidized to Fe3+ ions. This color change helps in determining the end point of the titration, where all the Mohr's salt has been oxidized and no more Fe2+ ions are present.
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.

The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
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.
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.
Why are there blue precipitate at the end of redox titration?
The blue precipitate may indicate the presence of excess indicator in the solution. In redox titrations, the indicator changes color when the reaction reaches its endpoint. If too much indicator is added, it can form a colored precipitate due to its reaction with the titrant, which can obscure the endpoint of the titration. It is important to carefully control the amount of indicator to avoid this issue.
What type of indicator is used during potassium permanganate titration?
Usually there is no indicator needed in potassium permanganate titrations as there will be an excess of manganate ions in the conical flask, turning the solution from colourless to pale pink.
Why thiosulphate titration is called as redox titration?
A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.
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.
