Is KMnO4 a base?
No, KMnO4 is not a base. It is a strong oxidizing agent commonly used in redox reactions to oxidize other substances.
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.
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.
Advantages and disadvantages of redox titration?
Advantages: Redox titration is versatile and can be used to analyze a wide range of substances, such as metal ions and organic compounds. It is also relatively simple and inexpensive compared to other types of titrations. Additionally, redox reactions typically produce clear and vivid color changes, making it easy to determine the endpoint. Disadvantages: Redox titrations can be sensitive to external factors such as pH, temperature, and presence of impurities, which can affect the accuracy and reliability of results. In addition, redox titrations may require more complex calculation methods due to the involvement of multiple oxidation states and stoichiometries.
Can KMnO4 be acidified with HCl and HNO3?
Yes, potassium permanganate (KMnO4) can be acidified with both hydrochloric acid (HCl) and nitric acid (HNO3) to increase its reactivity. Acidification helps to enhance the oxidizing power of KMnO4 in redox reactions.

What will you get if you mix KMnO4 and KI?
Unless the solution is made acidic or basic, the two will dissolve and form a solution of potassium ions, permanganate ions and iodide ions.
Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.
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
Why first colour changes when KMnO4 is added to ethanol and colour reappears when excess of KMno4 is added?
When KMnO4 is added to ethanol, it gets reduced to MnO2, causing the initial color change. However, when excess KMnO4 is added, MnO2 gets further oxidized back to KMnO4, resulting in the reappearance of the original color. This demonstrates the redox nature of the reaction between KMnO4 and ethanol.
What is the reaction equation of 2-butene with potassium permanganate?
2-butanol, CH3CH2CH(OH)CH3 + KMnO4 --------> butanone, CH3CH2COCH3 Butanol: OH | CH3-CH2-C-CH3 + KMnO4 | H Makes: Butanone: O CH3-CH2-C-CH3
What indicators used in redox titration?
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.
