Would you prepare calcium oxalate precipitate in a acidic or basic solution?
calcium oxalate precipitates only in basic solution
Why do you add zinc metal during titration of ferrous oxalate and potassium permangnate?
Zinc metal is added during the titration of ferrous oxalate and potassium permanganate to ensure that all the permanganate ions are used to oxidize the ferrous ions and not any other substances present in the solution. The zinc reduces any excess permanganate ions to colorless Mn2+ ions, allowing for a more accurate determination of the endpoint of the titration.
How do you prepare fresh ferrous sulphate?
To prepare fresh ferrous sulphate, dissolve ferrous sulphate heptahydrate crystals in water with gentle heating, stirring until completely dissolved. Allow the solution to cool and filter out any insoluble impurities. Store the solution in a tightly sealed container away from light and moisture.
How do you prepare 0.2N ferrous ammonium sulphate?
To prepare 0.2N ferrous ammonium sulfate, you would weigh out the appropriate amount of ferrous ammonium sulfate hexahydrate based on its molecular weight, dissolve it in distilled water, and then dilute the solution to the desired volume. Finally, check and adjust the concentration if needed by titration or dilution.
How do you prepare 1 N ferrous ammonium sulphate?
To prepare 1 N ferrous ammonium sulfate solution, dissolve 392.15 g of the compound in distilled water and dilute to 1 L. This will yield a solution with a concentration of 1 N.
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 is the chemical formula for ferrous oxalate?
Formula: FeC2O4
What is the formula for ferrous oxalate?
Fe(COO)2

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.
Calculate total no. of moles of k plus ions( source is potassium oxalate) oxalate ions ( sources are oxalic acid solutions and potassium oxalate) and Fe3 plus ions(source is ferrous ammonium sulfate)?
To calculate the total number of moles of K⁺ ions from potassium oxalate (K₂C₂O₄), you would double the moles of potassium oxalate since there are two K⁺ ions per formula unit. For oxalate ions (C₂O₄²⁻), you would also double the moles of potassium oxalate for the same reason. For Fe³⁺ ions from ferrous ammonium sulfate (Fe(NH₄)₂(SO₄)₂·12H₂O), each mole of the compound yields one mole of Fe³⁺ ions. Therefore, you'd simply take the moles of ferrous ammonium sulfate to determine the moles of Fe³⁺.
