Magnesium chloride hexahydrate, with the chemical formula MgCl2·6H2O, has the CAS number 7791-18-6. It appears as a white crystalline solid with no odor. The basic structure of magnesium chloride hexahydrate consists of one magnesium ion (Mg2+) and two chloride ions (Cl-) surrounded by six water molecules. This compound is highly soluble in water. Magnesium chloride hexahydrate is considered to be relatively safe for general use, but it should be handled with care to avoid ingestion or contact with skin and eyes. It is important to note that magnesium chloride hexahydrate may cause irritation or burns upon prolonged or repeated exposure. In case of accidental ingestion or contact, immediate medical attention is advised. It is also recommended to use protective equipment, such as gloves and goggles, when handling this compound.
Applicable Fields
De-icing Agent: Magnesium chloride hexahydrate is commonly used as a de-icing agent for roads and sidewalks during winter. Its purpose in this field is to lower the freezing point of water, preventing the formation of ice and facilitating snow removal. The mechanism of action involves the dissolution of magnesium chloride hexahydrate in water, which results in the release of heat and the formation of a brine solution that prevents ice formation.
Dust Control: This compound is also utilized as a dust control agent in various industries. Its purpose in this field is to suppress the generation and dispersion of dust particles, improving air quality and reducing the risk of respiratory issues. The mechanism of action involves the hygroscopic properties of magnesium chloride hexahydrate, which allows it to absorb moisture from the air and bind with dust particles, preventing their suspension.
Storage
Conditions: Store in a cool and dry place.
