Oxalic acid Hydrated 2H2O (C2H2O4) is a white, crystalline solid that is soluble in water and alcohol. A sample of oxalic acid with a purity of 99.6% would have the following properties:
1.Purity: The sample would be highly pure, with only a small percentage of impurities present.
2.Melting Point: The melting point of oxalic acid is around 189 °C (372 °F), so the sample should melt at or near this temperature.
3.Boiling Point: Oxalic acid decomposes before it boils, so it does not have a defined boiling point.
4.Solubility: Oxalic acid is highly soluble in water and alcohol, so the sample should dissolve readily in these solvents.
5.Acidity: Oxalic acid is a strong organic acid, and a 99.6% pure sample should have a high level of acidity.
6.Toxicity: Oxalic acid is toxic if ingested, inhaled, or absorbed through the skin, so proper handling and safety precautions should be taken when working with this substance.
Overall, a 99.6% pure sample of oxalic acid should exhibit the typical physical and chemical properties of this compound and can be used in various applications, such as cleaning, bleaching, and metal polishing.
