What is the normality of 1m oxalic acid?
The normality of 1M oxalic acid is 1N. This means that every mole of oxalic acid in 1 liter of solution has the capacity to donate or accept 1 equivalent of acid-base species.
Why can MnO2 stains on glassware be easily removed by rinsing with an oxalic acid solution?
MnO2 gets reduced by the reducing agent (in this case oxalic acid). But i do think the solution needs to be acidified to provide a anion ion for the Mn2+ ions that will be produced.
Will the normality of an h2c2o4 solution increase or decrease of the solution is stored in a clear bottle in a lighted room?
Oxalic acid is a stable compound.
What are oxalic acid?
Oxalic acid is an organic compound, a diprotic acid, with the molecular formula H2C2O4.
How is oxalic acid extracted from guava fruit?
A mash of guava fruit is oxidized in the presence of vanadium pentoxide. This produces the diesters of oxalic acid which are then hydrolyzed to oxalic acid.
Why there is no colour change when phenolphthalein is added to the oxalic acid?
In a weak acid solution phenophthalein has the "lactone" form which hasn't color.
Why would you add sulfuric acid to a mixture of oxalic acid and sodium oxalate?
This is an example of a buffer solution. if the sulfuric acid were added to a plain glass of water, it would have a massive change in pH. However, the buffer action of the oxalate-oxalic acid solution will decrease this change to something very minor (demonstrably to only hundredths or thousands, if the solution is made well, of the change it would have on pure water).
Which is stronger sulphuric acid or oxalic acid?
Sulfuric acid, as it disassociates almost 100% in solution.
What is the normality of 1m oxalic acid?
The normality of 1M oxalic acid is 1N. This means that every mole of oxalic acid in 1 liter of solution has the capacity to donate or accept 1 equivalent of acid-base species.
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
Calculate the required amount of oxalic aciddihydrate to prepare 200 mL of 0.50M oxalic acid solution?

How do you prepare standard solution of oxalic acid?
Oxalic acid (M.W.= 90 g/mol) is available in the lab as oxalic acid dihydrate crystals (M.W. = 126 g/mol). A standard solution of Oxalic acid or ethandioic acid can be used as a standard solution to standardise other alkali solutions because oxalic acid crystals are non-hygroscopic in nature. To prepare a 1 liter 1N solution of oxalic acid, follow these steps: 1. Carefully weigh 0.5 mol or 63 g of oxalic acid dihydrate crystals. This is because th n-factor of oxalic acid is 2 and so 1 mole of oxalic acid = 2 equivalents of oxalic acid. 2. Wash the 1 litre volumetric flask first with tap water (thrice), then with chromic acid solution (once but thoroughly) and finally with distilled water so as to remove any contaminants from the glassware. 3. Pour the crystals in the volumetric flask and add some distilled water. Shake the mix to dissolve the crystals in the solvent. 4. Make-up the volume to 1-litre by adding more distilled water.
Which of the following might you use to titrate an oxalic acid solution?
NaOH
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
Is oxalic acid a strong acid?
No. Oxalic acid is a weak acid.
What is the forumla for oxalic acid?
Oxalic acid is H2C2O4
What is the basicity of oxalic acid?
the basisity of oxalic acid is dibasic acid
