Key Properties
Zinc metal granulated extra pure is a high-purity granular form of elemental zinc, characterized by its silvery-gray appearance. With a purity of 99.5%, it is widely recognized for its effectiveness as a reducing agent in various chemical reactions, particularly in classical organic and inorganic chemistry. This form of zinc is notable for its high reactivity and is often employed in applications requiring precise chemical properties. The granulated form enhances its surface area, making it more efficient for use in laboratory and industrial settings.
Also known as Elemental Zinc, Zinc Granules.

- Substance
Zinc metal granulated extra pure appears as silvery-gray metallic granules, typically measuring between 1 to 5 mm in diameter. It has a melting point of approximately 419.5 °C and a boiling point of about 907 °C. The density of zinc is around 7.14 g/cm³, and it is insoluble in water but soluble in acids, such as hydrochloric acid, where it reacts to release hydrogen gas. The material has a relatively low vapor pressure at room temperature, making it stable under standard conditions.
