Ferrous sulfate is not used in redox titrations because it is easily oxidized by air in a laboratory setting, leading to inaccurate results. It is also easily hydrolyzed in the presence of water, affecting the stability and reliability of the titration. Alternative titrants with more stable and reliable properties, such as potassium permanganate or potassium dichromate, are preferred for redox titrations.

Why mohr's salt is used instead of ferrous sulphate in redox titration?
Mohr's salt (ammonium iron(II) sulfate hexahydrate) is used instead of ferrous sulfate in redox titrations because it is more stable and less prone to oxidation by air compared to ferrous sulfate. This helps in achieving more accurate and reliable results in redox titrations.
Why we use FAS rather than using ferrous sulphate for titration?
FAS (ferrous ammonium sulfate) is commonly used in redox titrations because it is more stable than ferrous sulphate and less prone to oxidation. FAS also allows for more accurate and reliable results due to its consistent purity and composition compared to ferrous sulphate.
Redox titrations of ferrous ion with KMnO4 why the HCl is not used in this reaction?
HCl is not used in redox titrations of ferrous ion with KMnO4 because it can react with KMnO4 and interfere with the titration process. HCl can reduce KMnO4, which would lead to inaccurate results by altering the equivalence point of the titration. Instead, a buffer solution is often used to maintain a constant pH during the titration.
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.
Is iodometric titration and redox titration is same?
Iodometric titration is a type of redox titration where iodine is used as the titrant. Redox titration is a broader category that encompasses any titration based on a redox reaction, not necessarily involving iodine. So while iodometric titration is a type of redox titration, not all redox titrations involve iodine.

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 sulfuric acid in redox titration?
Sulfuric acid is used in redox titrations to provide a medium with a very low pH, creating an acidic environment. This helps to stabilize certain redox reactions, especially those involving permanganate ions. Additionally, sulfuric acid can help in the reduction of certain compounds to ensure accurate titration results.
Why you use sulphuric acid in assay of ferrous sulphate?
Sulfuric acid is used in the assay of ferrous sulfate to convert the ferrous ions into ferric ions. This allows for the determination of the concentration of ferrous ions present in the sample through a colorimetric or titration method. Additionally, sulfuric acid helps in maintaining an acidic environment which stabilizes the oxidation state of iron during the analysis.
How many tipes of titration?
There are several types of titration based on the nature of the reaction being examined, including acid-base titration, redox titration, complexometric titration, and precipitation titration. Each type of titration is used to determine the concentration of a specific analyte in a sample.
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.
Is ferrous sulphate more reactive than silver nitrate?
Ferrous sulfate is more reactive than silver nitrate because it contains iron, a transition metal that readily undergoes redox reactions, whereas silver nitrate is a stable compound. Ferrous sulfate can act as a reducing agent in certain reactions, while silver nitrate is commonly used as a reagent in silver-related processes.
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.
