What else can I help you with?
Which of the following might you use to titrate an oxalic acid solution?
You could use a standardized solution of potassium permanganate (KMnO4) to titrate an oxalic acid solution. Potassium permanganate is a strong oxidizing agent that reacts with oxalic acid in an acidic medium, forming carbon dioxide gas, manganese dioxide, and water.
Why potassium permanganate is used as a self indicator in the titration of oxalic acid?
Potassium permanganate is used as a self-indicator in the titration of oxalic acid because the initial pink color of potassium permanganate is decolorized in the presence of oxalic acid due to its reducing properties. The endpoint of the titration is reached when all the oxalic acid has reacted with the potassium permanganate, causing the pink color to persist. This change in color helps in determining the equivalence point of the titration.
What is the reaction between potassium permanganate and sulphuric acid and oxalic acid?
Potassium Permanganate (KMnO4) reacts with Sulphuric acid (H2SO4) to produce Manganese Heptoxide (MnO7), water (H20) and Potassium Hydrogen Sulphate (KHSO4)2. The reactive species produced is Manganese Heptoxide (which is a very powerful oxidiser). The Manganese Heptoxide will oxidise the Oxalic acid (COOH)2 to Carbon dioxide (CO2).
Balanced equation for oxalic acid and potassium permanganate?
The balanced equation for the reaction between oxalic acid (H2C2O4) and potassium permanganate (KMnO4) in acidic solution is: 5 H2C2O4 + 2 KMnO4 + 3 H2SO4 → 10 CO2 + 2 MnSO4 + 8 H2O + K2SO4
Why you use dilute H2SO4 in titration permanganat and oxalic acid?
Dilute sulfuric acid is used in the titration of potassium permanganate with oxalic acid because it helps to maintain a stable pH and prevents the oxidation of oxalic acid by permanganate ions. This ensures accurate results by minimizing side reactions and interference.

Why is there colour change in the reaction between oxalic acid and potassium permanganate?
The color change in the reaction between oxalic acid and potassium permanganate is due to the reduction of purple potassium permanganate (MnO4-) to colorless manganese dioxide (MnO2). This reduction reaction causes the change in color from purple to colorless.

How is oxalic acid vs NaOH titration different from oxalic acid vs potassium permegnate titration?
In the titration of oxalic acid with NaOH, the acid-base reaction involves the neutralization of the acid by the base. However, in the titration of oxalic acid with potassium permanganate, the permanganate ion oxidizes the oxalic acid to carbon dioxide. This difference in reaction mechanisms leads to different equivalence points and color changes in the two titrations.
What happens when potassium permanganate is standardized with ethanedioic acid?
When potassium permaganate is mixed with ethanedioc acid the potassium permanganate Mn04- ion will be converted toMn2+, this means that you will observe the purple colour changing to a clear solution and the permanganate ion is oxidised. The Mn2+ will act as an auto catalyst speeding up the reaction, therefore a funny rate will occur, where the reaction is slow to start, before speeding up and slowing down again at the end. I read about this in chemistry review, so you can check it out there...http://www.york.ac.uk/depts/chem/chemrev/autocat.doc.
Procedure for retic stain in histology?
Deparaffinize and hydrate tissue sections. Stain with a 1% solution of potassium permanganate for 5 minutes. Rinse with tap water. Counterstain with a 1% solution of oxalic acid for 1-2 minutes. Rinse and dehydrate before mounting with a coverslip.
What is the order of reaction of the reaction between potassium permanganate and oxalic acid?
2Mn^2+ + 5IO4^- + 3H2O --> 2MnO4^- + 5IO3^- + 6H^+ ok so imagine the every time i wrote a ^ the thing after it is a super script and also that only numbers at the start of a molecule are written as big as the letter and the numbers in the middle should b subscript but i dont no how to do that unless im in a word document hope this helped. fi
When does potassium permanganate bleach the skin and when does it stain skin?
it depends on pH after browsing melanin bleach, it says that you require acid mixed with it it stain as MnO2 after oxidizing here and there, but removable with oxalic acid or citric acid
What is the reaction between potassium permanganate and sulfuric acid and oxalic acid?
Potassium permanganate and thiosulfate:2MnO4-(aq) + 10S2O32-(aq) + 16H+(aq) --> 5S4O62- + 2Mn2+(aq) + 8H2O(l)Potassium permanganate and oxalate:2MnO4-(aq) + 5C2O42-(aq) + 16H+(aq) + --> 10CO2(g) + 2Mn2+(aq) + 8H2O(l)Note:Potassium and sodium ions do NOT react, they are tribune-ions.
