| Sodium oxalate Usage And Synthesis |
| Physical Properties | White crystalline powder; density 2.34 g/cm3; decomposes around 250° C; sparingly soluble in water, 3.7 g/100 mL at room temperature; moderately soluble in boiling water, about 6.25 g/100 mL; the aqueous solution is practically neutral; insoluble in alcohol |
| Uses | Sodium oxalate is used as an analytical standard for standardization of potassium permanganate and other strong oxidizing agents. It also is used in finishing textiles, tanning leather, and blue printing. |
| Preparation | Sodium oxalate can be made by heating sodium formate at about 250°C:
2HCOONa → Na2C2O4 + H2
It also can be prepared by reacting oxalic acid with a dilute aqueous solution of sodium hydroxide followed by evaporation and crystallization. |
| Description | Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the molecular formula Na2C2O4. It is usually a white, crystalline, odorless powder, that decomposes at 250–270 °C.
Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions.
The mineral form of sodium oxalate is natroxalate. It is only very rarely found and restricted to extremely sodic conditions of ultraalkaline pegmatites. |
| Chemical Properties | White, crystalline powder. Soluble in water; insolu- ble in alcohol. |
| Physical properties | White crystalline powder; density 2.34 g/cm3; decomposes around 250° C; sparingly soluble in water, 3.7 g/100 mL at room temperature; moderately soluble in boiling water, about 6.25 g/100 mL; the aqueous solution is practically neutral; insoluble in alcohol. |
| Uses | Sodium Oxalate is obtained in such high purity and is so stable that it is used as a titrimetric standard. |
| Uses | Sodium Oxalate illustrate the elimination of broadening due to 2nd-?order quadrupolar effects leading to a 30-?fold increase in resolution compared to magic-?angle spinningin NMR of polycrystalline. |
| Uses | Finishing textiles, tanning and finishing leather; for standardizing potassium permanganate solution. |
| Definition | ChEBI: An organic sodium salt consisting of sodium and oxalate ions in a 2:1 ratio. |
| Preparation | Sodium oxalate can be prepared through the neutralization of oxalic acid with sodium hydroxide (NaOH) in a 1:2 acid-to-base molar ratio. Half-neutralization can be accomplished with NaOH in a 1:1 ratio which produces NaHC2O4, monobasic sodium oxalate or sodium hydrogenoxalate. |
