What is the balanced equation between potassium dichromate and oxalic acid?
The balanced equation between potassium dichromate (K2Cr2O7) and oxalic acid (H2C2O4) is: K2Cr2O7 + 3H2C2O4 -> Cr2(C2O4)3 + 2K2C2O4 + 4H2O
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).
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.
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.

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.

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.
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.
Why heat oxalic acid before titrate with potassium permanganate?
Heating oxalic acid before titrating with potassium permanganate helps to accelerate the reaction and improve the accuracy of the titration by ensuring that the reaction proceeds quickly and completely. Heating also helps to break down any impurities or complexes that may interfere with the reaction, leading to more precise results.
How to get the balance equation for a redox reaction of oxalic acid plus potassium permanganate?
To balance the redox reaction between oxalic acid (H2C2O4) and potassium permanganate (KMnO4), first write down the unbalanced equation. Then balance the atoms of each element on both sides of the equation, starting with elements that are not hydrogen or oxygen. Next, balance the oxygen atoms by adding water molecules. Finally, balance the hydrogen atoms by adding H+ ions. Count the charges on each side and balance them by adding electrons.
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.
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
