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?
With potassium permanganate and sulfuric acid, a redox reaction occurs where potassium permanganate is reduced to manganese(II) ions and sulfuric acid is oxidized. With oxalic acid, potassium permanganate undergoes a redox reaction where it is reduced to manganese(II) ions and oxalic acid is oxidized to carbon dioxide and water.
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 permanganate is standardized with ethanedioic acid (oxalic acid), the balanced chemical equation is KMnO4 + 5(C2O4^2-) + 16H+ → 2Mn^2+ + 10CO2 + 8H2O. The reaction is used to determine the precise concentration of the potassium permanganate solution. The reaction reaches a color change endpoint when all of the oxalic acid has reacted with the permanganate, allowing for calculation of the exact concentration of the KMnO4 solution.

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.
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.
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.
What is the reaction between potassium permanganate and sulfuric acid and oxalic acid?
With sulfuric acid, potassium permanganate will react to form manganese sulfate, water, and oxygen gas. With oxalic acid, potassium permanganate will react to form manganese dioxide, carbon dioxide, and water.
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
