ZINC HEPTA

Zinc sulfate heptahydrate (Zinc sulfate heptahydrate) is a kind of inorganic compound, the chemical formula is ZnSO4-7H2O, molecular weight is 287.55, it is a kind of white or yellowish crystals, easily soluble in water, slightly soluble in alcohol and glycerol, insoluble in liquid ammonia and ketone. Gradually weathering in dry air, losing water of crystallisation to white powder, losing water of crystallisation to anhydrous substance at 280℃, decomposing above 500℃.

The packaging of zinc sulfate heptahydrate typically comprises double-layer packaging with an inner plastic layer and an outer braided layer. The standard net weight is 25 kg per bag. It is of the utmost importance to exercise caution when transporting the container to prevent leakage, collapse, or falling, which could result in damage. Additionally, it is imperative to refrain from mixing the container with oxidants and edible chemicals, among other substances. It is imperative that the substance be safeguarded from exposure to sunlight, precipitation, and elevated temperatures.

With regard to safety, zinc sulfate heptahydrate has been found to cause moderate irritation to the eyes but no irritation to the skin. The misuse of this substance can result in a range of adverse effects, including nausea, vomiting, abdominal discomfort, diarrhoea and other symptoms of acute gastroenteritis. In more severe cases, it can lead to dehydration, shock and, in extreme instances, even death. The substance is harmful to the environment and has the potential to pollute water sources. The preparation of zinc sulfate heptahydrate can be achieved through the production of the material from zinc rhodochrosite, sphalerite, and other raw materials, or through the utilisation of the waste liquid of zinc sulfate. During the production process, the majority of anionic and select cationic impurities can be removed through crystallisation, resulting in the formation of products with coarse grains.
