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 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.
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.
Why is an indicator not used in a redox titration?
In a redox titration, an indicator is not used because the endpoint is determined by a change in the oxidation state of the analyte or titrant, rather than a change in pH or color. The endpoint is typically detected using a potentiometric method, such as a redox electrode, which directly measures the change in voltage.
Is starch redox indicator?
Starch is a complexometric indicator.
A redox reaction that doesn't require an indicator?
An example of a redox reaction that does not require an indicator is the reaction between zinc metal and hydrochloric acid to produce zinc chloride and hydrogen gas. This reaction can be observed directly by the effervescence of hydrogen gas being evolved without the need for an indicator to detect the change in oxidation states.

How does litmus in the litmus milk act as a redox indicator?
Litmus milk medium is skim milk to which the dye litmus has been added. Litmus is both a pH indicator and a redox indicator. It is pink at pH < 4.5, purple in middle pH's and blue at pH > 8.3. As a redox dye, in the absence of oxygen (reduced state) it's colorless (white due to milk) and in the presence of oxygen (oxidized state) it is purple.
What is the function of the phenanthroline solution that is added to the unknown iron?
phenanthroline is used as a redox indicator

What will form a spontaneous redox reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
How can you tell for sure that a redox reaction has happened?
if oxidation states change, it is a redox reaction
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.
