⚗️ Chemical & Physical Properties
Hydriodic acid is a colorless to pale yellow liquid with a strong, pungent odor reminiscent of rotten eggs. Its distinctive smell is characteristic of its chemical composition and can be easily detected even in small quantities.
The molar mass of hydriodic acid is approximately 127.91 g/mol, and its density is around 1.70 g/cm3 at room temperature. These values are significantly higher compared to common food items such as water (18.02 g/mol, 1 g/cm3) and sugar (342.30 g/mol, 1.59 g/cm3), indicating the heavier nature of hydriodic acid.
Hydriodic acid has a melting point of -51.05°C and a boiling point of 127.85°C. These temperatures are notably lower than those of common food items like butter (melting point of 32-35°C, boiling point of 100°C) and chocolate (melting point of 30-32°C, boiling point of 160-170°C), highlighting the extreme cold and heat conditions required for phase changes in hydriodic acid.
Hydriodic acid is highly soluble in water, forming a clear, colorless solution. It also exhibits low viscosity, flowing easily like water. In contrast, common food items such as salt and sugar dissolve in water but may have higher viscosities due to the presence of larger molecules or solid particles.
🏭 Production & Procurement
Hydriodic acid, a colorless or pale yellow liquid with a pungent odor, is primarily produced by reacting hydrogen gas with iodine. This reaction takes place in the presence of a catalyst, typically red phosphorus or a metal such as iron or vanadium. The resulting Hydriodic acid is then distilled to obtain the desired concentration.
Hydriodic acid can be procured from chemical suppliers in various concentrations, typically ranging from around 47% to 57%. It is commonly available in glass or plastic bottles, drums, or carboys. The transportation of Hydriodic acid must comply with hazardous material regulations due to its corrosive nature.
When transporting Hydriodic acid, proper labeling and packaging are crucial to ensure safe handling and prevent accidental exposure. The acid is usually transported in specialized containers that can withstand its corrosiveness. Proper training and adherence to safety protocols are essential for anyone involved in the handling and transportation of Hydriodic acid.
⚠️ Safety Considerations
Safety considerations for Hydriodic acid involve handling the compound with extreme caution due to its corrosive and toxic properties. When working with Hydriodic acid, it is important to wear appropriate personal protective equipment such as gloves, goggles, and a lab coat to prevent skin contact and inhalation of fumes. Additionally, Hydriodic acid should be used in a well-ventilated area to minimize exposure to potentially harmful vapors.
Hazard statements for Hydriodic acid include “causes severe skin burns and eye damage” and “may be fatal if swallowed or inhaled.” These statements highlight the serious health risks associated with exposure to Hydriodic acid, emphasizing the need for proper safety measures when handling the compound. It is crucial to follow all recommended precautions to avoid accidents and potential harm.
Precautionary statements for Hydriodic acid advise individuals to “wear protective gloves/eye protection/face protection” and “do not breathe dust/fume/gas/mist/vapors/spray.” These statements underscore the importance of using personal protective equipment and working in a well-ventilated area to minimize the risk of exposure to Hydriodic acid. Following these precautions can help ensure the safety of individuals handling the compound.
