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.
Could you prepare oxalic acid by adding hcl to a solution og sodium oxalate?
Yes, oxalic acid can be prepared by adding hydrochloric acid (HCl) to a solution of sodium oxalate. The reaction that occurs is double displacement reaction where sodium chloride and oxalic acid are formed. Oxalic acid can be obtained by precipitating it out of the solution by adjusting the pH.
Chemical reaction in the preparation of citric acid from calamansi?
To prepare citric acid from calamansi, the main chemical reaction involved is the conversion of citric acid in the fruit juice to its calcium citrate salt. This reaction occurs when calcium hydroxide is added to the calamansi juice, resulting in the formation of insoluble calcium citrate precipitate. The precipitate is then filtered and treated with sulfuric acid to regenerate citric acid in its pure form.
How neutral fecl3 solution prepare?
Take 1 ml FeCl3 solution. add ammonia solution drop wise till brown precipitate just form. Now again add FeCl3 solution till brown precipitate just dissolve. This is your Neutral FeCl3 solution.
How do you prepare HgNH2Cl?
To prepare HgNH2Cl, first dissolve mercury(II) chloride (HgCl2) in water. Then add aqueous ammonia (NH3) to the solution until a white precipitate of mercury(II) amine chloride (HgNH2Cl) forms. The precipitate can be filtered and washed to isolate the compound.

How do you prepare tollen reagent?
To prepare Tollens reagent, mix aqueous silver nitrate with ammonia solution until a precipitate forms. Then add sodium hydroxide solution to redissolve the precipitate and form the final reagent. It is used to test for the presence of aldehydes in a reaction.

How will you prepare chrome alum?
To prepare chrome alum, dissolve potassium dichromate in water until fully dissolved. Then, add aluminum sulfate solution gradually with stirring to form a precipitate. Allow the solution to stand and crystallize to obtain chrome alum crystals.
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

Give the test for carbon dioxide?
The most common colorimetric test for carbon dioxide gas involves using limewater (calcium hydroxide solution). When carbon dioxide is bubbled through limewater, it forms a white precipitate of calcium carbonate, indicating the presence of the gas. Additionally, using a pH indicator paper that changes color in the presence of carbon dioxide can also be a simple test.
HOW TO Prepare alum from scrap aluminum?
To prepare alum from scrap aluminum, begin by cutting the aluminum into small pieces and dissolving it in a sodium hydroxide solution. Filter out any impurities, then add sulfuric acid to the solution to precipitate aluminum hydroxide. Lastly, treat the aluminum hydroxide with sulfuric acid and allow the solution to evaporate to obtain alum crystals.
How do you prepare 0.1 N Na2C2O4 solution?
To prepare a 0.1 N sodium oxalate (Na2C2O4) solution, first calculate the required mass by using the formula: mass (g) = normality (N) × equivalent weight (g/equiv) × volume (L). The equivalent weight of Na2C2O4 is 126.07 g/mol divided by 2, since it can donate two moles of oxalate ions (C2O4^2-), resulting in 63.035 g/equiv. Weigh out the appropriate mass of Na2C2O4, dissolve it in distilled water, and then dilute to the desired final volume, ensuring thorough mixing.
