Yes, these are two names for the same substance with the formula Zn(NO₃)₂·6H₂O. The English name “zinc nitrate hexahydrate” is used in documents. When purchasing, it is important to check not only the name but also GOST 5106-77, the mass fraction of the main substance, the content of water-insoluble substances, sulfates, chlorides, iron, lead, acids and alkaline impurities. This helps accurately match the batch to the enterprise’s incoming inspection requirements.
When receiving zinc nitrate hexahydrate, the integrity of the bags, labelling, production date, quality certificate and the batch’s compliance with GOST 5106-77 are checked. Laboratory control focuses on the content of the main substance, insoluble residue, sulfates, chlorides, iron, lead, acidity calculated as HNO₃ and alkaline impurities. Visually, the product should be colourless transparent crystals without wetting, contamination, dense lumps or foreign inclusions.
Zinc nitrate hexahydrate is classified as an oxidising substance, so on contact with flammable materials it can intensify ignition and active combustion. For a warehouse this means separate storage from organic substances, reducing agents, packaging waste, wood dust and other incompatible materials. When working with a batch it is important to prevent contamination of the crystals by foreign substances. This approach reduces the risk of an emergency situation and helps preserve product quality until transfer into production.
Zinc nitrate hexahydrate is stored in a dry, unheated, well-ventilated warehouse, at a temperature not exceeding 30°C and in sealed factory packaging. In an open container, the product can lose stability and retain its stated properties less well, so bags should not be left open unnecessarily. Packaging is placed on pallets, separately from moisture, flammable materials and incompatible reagents.
