1. Cleaning agent: Oxalic acid is a powerful cleaning agent and is commonly used for removing tough stains and rust from metal surfaces. It can effectively remove lime deposits, tarnish, and mineral build-up from various surfaces.

2. Bleaching agent: Oxalic acid is used as a bleaching agent in industries such as textile, wood, and pulp. It can remove color from natural fibers and materials to achieve a pure white appearance.

3. Wood stain removal: Due to its ability to dissolve organic materials, oxalic acid is often used to remove stubborn stains and marks from wooden surfaces. It is commonly used to restore and renovate old furniture by removing water stains, ink marks, and other blemishes.

4. Metal cleaning and polishing: Oxalic acid can be used to clean and polish various metals, including brass, copper, and stainless steel. It can effectively remove tarnish and restore shine to the metal surfaces.

5. Rust removal: The acidic nature of oxalic acid allows it to dissolve rust. It is commonly used for removing rust from metal tools, machinery, and household items.

6. Chelating agent in laboratories: Oxalic acid can form stable complexes with metal ions, making it useful as a chelating agent in laboratories. It is used to dissolve and analyze metal compounds in various chemical analyses.

7. Miticide in beekeeping: Oxalic acid is used as an organic miticide in beekeeping to control varroa mites, which can be harmful to honeybee colonies. It is applied as a vapor or as a diluted solution to treat beehives.

8. Reducing agent in chemical synthesis: Oxalic acid can act as a reducing agent in various chemical reactions. It can be used to reduce metal ions to their elemental form or to convert other organic compounds into simpler molecules.

It is important to note that oxalic acid is a toxic and corrosive substance, and appropriate safety precautions should be taken when handling it.

Safety precautions and hazards associated with Oxalic acid

Oxalic acid is a toxic and corrosive substance, and it should be handled with caution. Here are some safety precautions and hazards associated with Oxalic acid:

1. Personal protective equipment (PPE): Wear appropriate PPE, such as gloves, protective eyewear, and a lab coat or apron when handling Oxalic acid.

2. Inhalation hazards: Oxalic acid can release toxic fumes when heated or dissolved in water. It is important to work in a well-ventilated area or use a fume hood to prevent inhalation of these fumes.

3. Skin contact hazards: Oxalic acid can cause severe skin burns and irritation. Avoid direct skin contact with the acid, and immediately wash any exposed skin with soap and water.

4. Eye contact hazards: Oxalic acid can cause severe eye burns and damage. In case of eye contact, rinse the eyes with water for at least 15 minutes and seek medical attention immediately.

5. Ingestion hazards: Oxalic acid is highly toxic if ingested. It can cause severe damage to the gastrointestinal system. Never consume or ingest Oxalic acid, and seek immediate medical attention if accidental ingestion occurs.

6. Fire hazards: Oxalic acid is combustible under certain conditions. Keep it away from open flames and sources of ignition.

7. Storage and handling: Store Oxalic acid in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers. Keep the acid containers tightly closed when not in use, and use appropriate containers for storing and transporting.

8. Spill and leak precautions: In case of a spill, immediately contain the area and prevent the acid from spreading. Avoid direct contact with the spilled material and use appropriate PPE while cleaning it up. Neutralize the spill with a suitable base (such as baking soda or lime) and dispose of the waste according to local regulations.
