Ferrous chloride, also known as iron(II) chloride, is a white crystalline solid that is highly soluble in water. It is commonly used in various applications, including water treatment, where it serves as a coagulant and flocculant to remove impurities, including phosphates, and aids in the clarification of wastewater. In the textile industry, it is used as a mordant to fix dyes. Additionally, ferrous chloride is used in the etching of metals and in the production of inks and pigments.
Due to its corrosive nature, ferrous chloride can cause irritation to the skin, eyes, and respiratory tract. It is important to handle this compound with care and to follow safety guidelines and regulations. Storage should be in a cool, dry place, away from moisture and incompatible materials. When used in industrial processes, proper safety measures, including the use of personal protective equipment, should be taken to prevent exposure and ensure safe handling.
Ferrous chloride is sensitive to temperature and humidity fluctuations, and it is important to store it in a cool and dry environment to prevent degradation and clumping. Avoid exposing it to extreme temperatures or high humidity levels, as this can impact its chemical properties. A temperature range between 15°C and 25°C (59°F and 77°F) with a humidity level below 60% is generally recommended, but check the specific storage requirements provided by the manufacturer.
