Why you use oxalate potassium in formol titration?
In formol titration, amino acids with formaldehyde are titrated with NaOH to measure the amount of amino acids in the solution. Potassium is also necessary for this titration and is supplied by using potassium oxalate. If calcium is present, it will react with the NaOH to form Ca(OH)2. This will make it appear to need more of the NaOH solution (and overestimate the titration). Potassium oxalate will chelate the calcium, and prevent it from reacting (forming calcium oxalate).
Why potassium oxalate is acidified before titration?
If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permanganate will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so it's important to stay in this range.
Is there a different between potassium oxalate and potassium acid oxalate?
sorrel salt: potassium hydrogen oxalate or potassium hydrogen oxalate, KHC2O4 (sal acetosella, salt of lemon). Here only one 'H' is replaced with 'K' in oxalic acid to get HOOC-COOK. Potassium oxalate is KOOC-COOK.
Why do you have to warm the oxalate solution before performing titration?
because if the temperature is too low the interaction between the oxylate and potassium permanganate will move too slow?? why IDK
How can you prepare ferrous oxalate?
Add ferrous chloride solid to saturated aqueous solution of oxalic acid then to expel the HCl gas then saturated solution is allow to cool the crystals of ferrous oxalate settled down with in few minutes remove the excess liquid and get the dry compound.

Ferrous oxalate reaction with potassium permanganate?
Potassium permangante, being a very strong oxidizing agent, oxidizes both the Fe2+ ion and the oxalate ion. Redox reactions are shown below: Oxalate oxidation: 2MnO4- + 16H+ + 5C2O42- ---> 2Mn2+ + 8H2O + 10CO2 Iron(II) oxidation: MnO4- + 8H+ + 5Fe2+ ---> Mn2+ + 4H2O + 5Fe3+ Moreover, if one needs to determine the exact percentage of oxalate and ferrous ions in solution, a titration is carried out using the permanganate, which will react with both the oxalate and ferrous ions. But, the carbon dioxide is liberated from the soution now, and zinc is added whch reduces the Iron(III) back to Iron(II). Another titration is then carried out using the permanganate, which gives a reading for the Iron(II) in solution only.
How can you separate ferrous oxalate from titanium oxalate?
If you want to separate ferrous oxalate from titanium oxalate, you need to put them in an alkaline solution and introduce heat. They should break apart into their two respective oxolates.

What are the different primary standards used in titration?
Different primary standards used in titration are as follows 1. Acids - constant boiling HCl, benzoic acid 2. Base - sodium carbonate, HgO, Borax 3. Oxidizing agent - Potassium Dichromates, Potassium bromate, potassium iodate, iodine 4. Reducing agent - iodine, sodium oxalate, arsenous oxide

What composition is Potassium oxalate?
KOOC-COOK.K2C2O4
