? Detailed Introduction of Oxalic Acid

✔ What is Oxalic Acid?

Oxalic Acid (C₂H₂O₄) is a highly versatile organic acid commonly found in industrial, chemical, and food applications. It exists in two forms:

• Oxalic Acid Anhydrous (pure form)

• Oxalic Acid Dihydrate (with two water molecules per unit)

Nó làodorless, colorless, and highly soluble in water, making it effective in cleaning, bleaching, and chemical processing.

✔ Số CAS & Công thức hóa học:

Oxalic acid, with the chemical formula C2H2O4, is an organic compound that exists as a colorless crystalline solid at room temperature. It is classified as a dicarboxylic acid (due to having two carboxyl groups) and is both the simplest and among the strongest of these types of acids. It’s often found in its dihydrate form (C2H2O4·2H2O) which makes it less concentrated. However, oxalic acid is still quite potent and should be handled with care due to its toxic and corrosive nature.

1. Cleaning: Oxalic acid can effectively remove mineral deposits, rust, bleach stains, and other types of grime, which makes it widely used as a cleaner for a variety of surfaces, including wood and stone. It is particularly effective at removing rust stains and is therefore often used in boat cleaning and maintenance.
2. Bleaching Agent: It is used as a reducing agent for photography and ink removal, due to its potent bleaching properties.
3. Industrial Uses: The compound is used prominently in the dyeing processes and colorant production. It is used as a mordant in dyeing processes, which aids in making the dye color stick to the fabric firmly.
4. Dược phẩm: Oxalic acid also plays a role in the production of certain pharmaceuticals.
5. Metallurgy: In metallurgy, it is used as a precipitating agent.
