Why we ad sulpheric acid with oxalic acid?
we add sulpheric acid with oxalic acid to stable the ions when titrated against KMNO4
Can oxalic acid be used for standardization of strong base?
Yes, in fact it is the only acknowledged acid (DIN, ASAC, NEN) to be used with standardisation in analytical titration chemistry (volumetrics > > titrimetrics > acidimetry). By the way, it is also used in oxidimetric standardisation.
What are oxalic acid?
Oxalic acid is an organic compound, a diprotic acid, with the molecular formula H2C2O4.
What is the chemical name of oxalic acid?
The chemical name of oxalic acid is ethanedioic acid.
What is the name for the chemical formula H2C2O4?
The chemical formula H2C2O4 represents oxalic acid. Oxalic acid is a dicarboxylic acid that is commonly found in plants and can also be produced synthetically for various industrial purposes.

Could you prepare oxalic acid by adding hcl to a solution og sodium oxalate?
Yes, oxalic acid can be prepared by adding hydrochloric acid (HCl) to a solution of sodium oxalate. The reaction that occurs is double displacement reaction where sodium chloride and oxalic acid are formed. Oxalic acid can be obtained by precipitating it out of the solution by adjusting the pH.
Which indicator is used in titration of oxalic acid with HCl?
Both HCl and oxalic acid are acids. Therefore, since there is no alkali present, these compounds do not undergo neutralization. So there is no suitable indicators for the addition of these two reagents.
Is it necessary to know the exact concentration of oxalic acid to determine the concentration of the base?
No, it is not necessary to know the exact concentration of oxalic acid if you are titrating it with a base. You can determine the concentration of the base by measuring the volume of the base solution required to neutralize the acid solution.
Could you prepare oxalic acid by adding HCl to a solution of sodium oxalate cooling it to room temp and filtering the resulting mixture?
No we cannot prepare Oxalic acid by the given method. Solubility of Sodium Oxalate is less in comparison to solubility of Oxalic acid. So whatever oxalic acid is formed will remain in the solution and cannot be precipitated out in the form of solid

What is the forumla for oxalic acid?
Oxalic acid is H2C2O4
Does Rhubarb have acid in it?
no Oxalic acid is found in rhubarb
Is oxalic acid a strong acid?
No, oxalic acid is considered a weak acid. It dissociates partially in water to release hydrogen ions.
What is the name of acid present in spinach?
The acid present in spinach is oxalic acid.
Why oxalic acid is heated before titration with KMnO4?
Heating oxalic acid before titration with KMnO4 helps to remove any water of crystallization, making the compound anhydrous. This ensures accurate measurement of the substance being titrated and helps to prevent interference from water during the titration process. Additionally, heating can help to dissolve the oxalic acid more effectively, ensuring a more efficient reaction during titration.
Is rhubarb an alkali?
It is an acid - Oxalic acid
