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 type of reaction is NaOH with Oxalic acid?
The reaction between NaOH and oxalic acid is a neutralization reaction, resulting in the formation of sodium oxalate and water. Oxalic acid is a dicarboxylic acid that can react with a base like NaOH to form a salt and water.
What is valency oxalic acid?
Oxalic acid has a valency of 2, as it can donate two hydrogen ions in a chemical reaction. This makes it a dicarboxylic acid.
How do you prepare saturated solution given 1gram of oxalic acid in 7g of water?
To prepare a saturated solution of oxalic acid, dissolve 1 gram of oxalic acid in 7 grams of water at a given temperature until no more oxalic acid can dissolve. This will result in a saturated solution where the maximum amount of oxalic acid has dissolved in the water at that temperature.
What are the reactions between oxalic acid and copper?
Oxalic acid can react with copper to form copper oxalate, which is a green solid. This reaction involves the exchange of ions between the oxalic acid and copper ions. The reaction is often used for analytical purposes to detect the presence of copper in a solution.

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.

Does aqueous ammonia react with oxalic acid?
Yes, aqueous ammonia can react with oxalic acid to form the ammonium salt of oxalic acid, which is ammonium oxalate. This reaction involves the exchange of ions between ammonia and oxalic acid molecules.
Why there is a need to warm the solution of sulfuric acid and oxalic acid during redox titration?
Warming the solution of sulfuric acid and oxalic acid during redox titration increases the reaction rate, making the titration process faster and more efficient. The elevated temperature helps to ensure that the reaction between the two compounds proceeds to completion, resulting in more accurate and reliable titration results.
Can oxalic acid be titrated by HCl?
Yes, oxalic acid can be titrated by HCl because oxalic acid is a diprotic acid and can react with HCl in a simple acid-base reaction. The titration involves determining the volume of acid required to neutralize the oxalic acid solution, which can be used to calculate the concentration of oxalic acid.
Why 2N sulphuric acid is used in oxalic acid estimation?
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
How do you prepare oxalic acid?
how do prepare 0.1 N Oxalic acid
What products are formed from the reaction of H2C2O4 H2O?
The reaction of oxalic acid (H2C2O4) with water (H2O) can lead to the formation of oxalic acid dihydrate. This compound is often used in chemical synthesis and as a reducing agent.
