Basic information

Nature
1. Appearance: Colorless crystalline solid, showing a crystal shape similar to sugar
2. Solubility: oxalic acid has a high solubility in water and can react quickly with water to form oxalic acid solution.
3. Acid: oxalic acid is a double acid that can release two protons (H+) and react with the base to form the corresponding salt.
4. Oxidation: oxalic acid can be used as a reducing agent to react with some oxidants, such as hydrogen peroxide (H2O2).
5. Decomposition: under high temperature or strong acid conditions, oxalic acid can be decomposed into carbon dioxide (CO2) and carbon monoxide (CO).

Use
1. Metal cleaning agent: oxalic acid can dissolve oxides, alkali deposits and scale on the metal, often used to clean metal surfaces, such as stainless steel, copper, aluminum, etc.
2. Dye industry: oxalic acid can be used as an intermediate for dye printing and dyeing, for the synthesis of dyes and pigments.
3. Catalyst: oxalic acid can be used as a catalyst for some chemical reactions, such as esterification reaction, synthesis of carboxylate, etc.
4. Health and medical use: oxalic acid can be used as cleaning agent, disinfectant and laxative. It is also used in some drugs to treat certain urinary stones.
5. Electronics industry: oxalic acid can be used as a cleaning and polishing agent for electronic components.
6. Textile industry: oxalic acid can be used as a solvent for cellulose fibers, for the processing of cellulose fibers.
7. Cleaning agent: oxalic acid can be used as a cleaning agent, which can effectively remove the oxide layer, stains and calcium scale on the metal surface. Common applications include cleaning stainless steel appliances and cleaning toilets and bathtubs.
8. Battery: oxalic acid can be used to manufacture potassium ferricyanide batteries, iron and aluminum batteries and some other dilute electrode batteries.

Secure
1.Oxalic acid has a certain toxicity, should pay attention to safe operation and appropriate protective measures when using.
2. Oxalic acid is corrosive, please pay attention to safety when using
