Application
Sodium arsenate dibasic heptahydrate serves multiple purposes primarily due to its role as a source of soluble arsenic. This odorless compound appears as white or colorless crystals and becomes anhydrous when heated to 212°F. In an aqueous solution, it exhibits alkaline properties and is water-soluble. It is particularly used in dyeing and printing with Turkey-red oil, and also plays a crucial role in veterinary medicine, where it is applied as a treatment for various ailments, including parasitic infections, skin and blood diseases, rheumatism, and asthma. However, it is important to note that sodium arsenate dibasic heptahydrate is incompatible with strong oxidizing agents, strong acids, and metals like iron, aluminum, and zinc when water is present, as these conditions may lead to unwanted reactions.
