Best Answer

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.

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


Could you prepare oxalic acid by adding hcl to a solution og sodium oxalate?

Yes, it is possible to prepare oxalic acid by adding hcl to a solution og sodum oxalate. The balance equation would be C2O4Na2 + 2HCl -----> 2NaCl + C2O4H2.

How do you prepare 100ml 0.1M of oxalic acid solution?

Firstly you find how much solid oxalic acid you will need, via n = c/v, where: n= number of molesc = concentrationv = volume, in this casen=(.1/.25)=.4 molesNow, from this we can find how many grams of solid oxalic acid we will need, usingn=m/M, wheren= number of molesm = massM = molecular mass, in this casem = nM (through manipulation of the equation)= (.4)(90.03)= 36.012 gNow, you would need to take this pure oxalic acid and add it to a 250mL volumetric flask and fill to you reach the marker.


Is it necessary to rinse the conical flask with some standard solution of oxalic acid before use?

I believe it is necessary to rinse the conical flask with oxalic acid before use, unless you are sure that the conical flask is really clean and dry before use. However to prevent having any types of unwanted chemical reaction when you pour the oxalic acid in the flask, it is best to rinse it with oxalic acid before use, so that there will not be errors like e.g. there is no pinkish color formed in the solution when you add the color indicator in the oxalic acid when doing titration.

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.
