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 ferrous sulphate is not used in redox titration?
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.
Can we perform redox titration without heatng?
Yes, redox titrations can be performed without heating, depending on the reaction kinetics and the nature of the redox couple involved. Some redox reactions may proceed efficiently at room temperature without the need for heating. However, heating is often employed in redox titrations to accelerate the reaction rate and ensure completion within a reasonable time frame.
What is the reaction between KMnO4 and H2O2?
The reaction between KMnO4 (potassium permanganate) and H2O2 (hydrogen peroxide) is a redox reaction where the permanganate ion is reduced to manganese dioxide and oxygen gas is produced. The overall reaction can be represented as: 2 KMnO4 3 H2O2 - 2 MnO2 2 KOH 2 H2O 3 O2
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.

Why H2So4 is used in acidification of KMno4 solution not HCl or HNo3?
H2SO4 is used in acidification of KMnO4 solution because it is a stronger acid compared to HCl or HNO3, which ensures complete dissociation of the acid and provides a higher concentration of H+ ions for the redox reaction to occur efficiently. Additionally, H2SO4 is not easily oxidized by KMnO4, unlike HCl or HNO3 which could interfere with the redox reaction.
Why is dilute h2so4 most suitable as compared to hcl and hno3 in kmno4 titrarion?
Dilute H2SO4 is preferred over HCl and HNO3 in KMnO4 titrations because H2SO4 does not oxidize the Mn present in KMnO4, maintaining its stability. On the other hand, HCl and HNO3 can oxidize Mn in KMnO4, interfering with the titration results. Additionally, H2SO4 helps to acidify the solution and provide the necessary hydrogen ions for the reduction-oxidation reaction to proceed effectively.
Why redox titration is more useful than acid base titration?
Redox titrations can be used to quantify substances that do not react with acids or bases, such as reducing agents. This makes redox titrations more versatile in terms of the types of substances that can be analyzed compared to acid-base titrations. Additionally, redox titrations are more sensitive and can provide more precise results in certain cases.
When KMnO4 and NaOH are mixed together what is formed?
Na2SO3 + KMnO4 ---> K2SO3 + NaMnO4 All solutions are aqeous. It's a simple double replacement reaction. Its a Redox Equation not a double replacement KMnO4 is a common oxidizing agent im not sure about the answer but i guess it has to change KMnO4 into MnO
Why do you add H2SO4 instead of HCL in redox titration?
H2SO4 is preferred over HCl in redox titrations because HCl can release Cl2 gas during the reaction, which can interfere with the titration results. H2SO4 provides the necessary acidic conditions for the redox reaction without introducing additional complications.
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.
