ammonium oxalate is added to calcium carbonate because in the reaction between the two a crystal is formed that contain the Ca+2 ion. This is useful because if you have a sample of sodium carbonate with an unknown molarity you can use the oxalate to extract this calcium and determine what the molarity of the unknown solution was

What is the equation when ammonium oxalate is added in calcium carbonate solution?
(NH4)2C2O4 + CaCl2 ---> 2NH4Cl + CaC2O4
Would you prepare calcium oxalate precipitate in a acidic or basic solution?
calcium oxalate precipitates only in basic solution
What is the normality of 0.1M ammonium oxalate?
Ammonium oxalate is difunctional and so the normaility is 0.2N.
What is (NH4)2C2O4?
(NH4)2C2O4 is the chemical formula ammonium oxalate.
What is the chemical abbreviation for Ferric Ammonium Oxalate?
oxalate
Why ammonium oxalate is added in calcium carbonate solution?
Calcium carbonate is rather INsoluble, so there is no solution of it. I do not know why ammonium oxalate is added to a calcium carbonate solution. Calcium oxalate will then precipitate out of the solution. The ammonium and carbonate will create a weakly bond compound. Actually, more of the ammonium ion will be in solution as free ammonia and more of the carbonate ions will be in solution as free carbon dioxide. That is the nature of those two substances. So, you will have a solution that has a calcium oxalate precipitant on the bottom and is slowly giving off ammonia and carbon dioxide.

What is the equation when Ammonium oxalate is added in calcium chloride solution?
(NH4)2C2O4(aq) + CaCl2(aq) yields CaC2O4 +2NH4Cl(aq)
Would you prepare calcium oxalate precipitate in a acidic or basic solution?
calcium oxalate precipitates only in basic solution
What is the balanced chemical equation when calcium nitrate is reacted with ammonium oxalate?
Ca(NO3)2 + (NH4COO)2 = Ca(COO)2 + 2 NH4NO3 Calcium oxalate is a white precipitate.
What is the normality of 0.1M ammonium oxalate?
Ammonium oxalate is difunctional and so the normaility is 0.2N.
What is the chemical formula of ammonium oxalate monohydrate?
Ammonium oxalate monohydrate is (NH4)2C2O4•H2O
What is (NH4)2C2O4?
(NH4)2C2O4 is the chemical formula ammonium oxalate.
What is the chemical abbreviation for Ferric Ammonium Oxalate?
oxalate
Which is the chemical formula for ammonium oxalate monohydrate?
Formula of ammonium oxalate monohydrate: (NH4)2C2O4.H2O
What is the equivalent weight of sodium oxalate?
mw : 134 /2= 67
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).
