As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before ..
we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
What else can I help you with?
What are kmno4?
acidicness number of kmno4
What is Valency of k in kmno4?
tell me about the vlance of Mn in KMnO4
What does KMnO4 stands for?
It stands for Potassium Permanganate and is usually used to control color, taste, and odors.
What elements are in potassium permangante?
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
What indicator uses the acronym 'MA'?
The indicator that uses the acronym 'MA' is Moving Average. It is a widely used indicator used to trade trends.
Why in titration of kmno4 no indicator is used?
In the titration of KMnO4, no indicator is used because KMnO4 is a self-indicating titrant. It undergoes a color change from purple to colorless (or brown) at the endpoint of the titration, which makes it unnecessary to add an external indicator. The precise endpoint can be easily detected visually, making the use of an indicator redundant.
Advantages and disadvantages using KMnO4 in redox titrimetry?
The advantage is that it acts as a self-indicator i.e. Does not need any indicator while the disadvantage is that it is a strong oxidizing agent therefore reacts vigorously and very fast.
Why kmno4 is used to detect the amount of h202 used?
The color change with oxidation of the permangante changes from purple to clear allows the titration to be conducted without using a seperate indicator.
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.
Chemical symbol for permanganate?
The formula for potassium permanganate is KMnO4
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.
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.
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 is the compound KMnO4?
Potassium permanganate (KMnO4) is a dark purple, crystalline compound that is commonly used as an oxidizing agent in various chemical reactions. It is soluble in water and known for its powerful oxidizing properties.
What are kmno4?
acidicness number of kmno4
Why is NaOH used in oxidation using KMnO4?
NaOH is used in oxidation reactions with KMnO4 to maintain a basic pH, which helps stabilize KMnO4. This ensures that the permanganate ion (MnO4-) remains in its most reactive form, allowing more efficient oxidation of organic compounds. Additionally, NaOH helps to dissolve solid KMnO4 and facilitates the reaction process.
