Is sodium oxalate aqueous?
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.
What type of compound is sodium oxalate?
Sodium oxalate is an organic sodium salt consisting of sodium and oxalate ions in a 2:1 ratio. It has a role as a poison and a reducing agent. It is an oxalate salt and an organic sodium salt. It contains an oxalate(2-).
Is sodium oxalate a precipitate?
Under typical, co-precipitation conditions, sodium oxalate will precipitate as needles. Some of those needles may be recycled with the trihydrate seed and the oxalate needles will themselves act as seed sites to promote the formation of more oxalate as needles.
What is oxalate salt?
Oxalic acid has the ability to form strong bonds with various minerals, such as sodium, potassium, magnesium, and calcium. When this occurs, the compounds formed are usually referred to as oxalate salts. Thus, “oxalate” usually refers to the salt forming ion of oxalic acid.
Is sodium oxalate hygroscopic?
Sodium Oxalate or disodium oxalate is a sodium salt of oxalic acid. It is a colourless, crystalline, odorless powder with low water-solubility. Disodium oxalate is not hygroscopic.

Is Na2C2O4 a solid?
Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na2C2O4. It is a white, crystalline, odorless solid, that decomposes above 290 °C.
Is sodium oxalate an acid or base?
Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na2C2O4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions.

Is ammonium oxalate hygroscopic?
The measured hygroscopic growth factor (HGF) of OxA at 90% RH was 1.47. We found that the HGF of ammonium oxalate (NH4-Ox) was larger than that of OxA, whereas HGFs of sodium, calcium, and magnesium oxalates (Na-Ox, Ca-Ox, and Mg-Ox) were smaller than that of OxA particles.
Is na2c2o4 ionic or covalent?
The given compound is an ionic compound. It constitutes a cation Na+ and a polyatomic ion (C2O4)2− ( C 2 O 4 ) 2 − , named as the sodium ion and oxalate ion respectively.
