Question

Define the granulated zinc.

Answer 1

• The zinc metal with high surface area and large particle size are called zinc granules.
• It is preferred for laboratory preparation of hydrogen gas because it has a high surface area, which facilitates reaction in a better way.
• It can yield hydrogen gas when reacted with acids.
• Zinc granules are unevenly shaped particles of zinc that are formed by pouring molten zinc into water.
• Zinc granules have a greater particle size as compared to zinc powder.
• Zinc is employed in the manufacture of hydrogen gas in the form of granules due to its enormous surface area.
• Both zinc granules and zinc have the same physical properties, although chemical attributes differ only slightly.
• In the laboratory preparation of hydrogen, zinc granules are favored over pure zinc because the impurity contained in granulated zinc is copper, which has a catalyzing effect and speeds up the reaction rate.
