What bluish white metal is known for its corrosive resistance and low melting point?

• A. Aluminum
• B. Copper
• C. Zinc
• D. Iron

Answer: (C)

The bluish white metal known for its corrosive resistance and low melting point is zinc. Zinc's properties make it particularly suitable for various applications, including galvanizing steel to protect it from corrosion. It has a melting point of around 420 °C (788 °F), which is considered low compared to other metals in the same category. Zinc's natural corrosion resistance stems from its ability to form a protective oxide layer on its surface when exposed to moisture, which further enhances its longevity and durability in various environments. In contrast, aluminum, while also corrosion-resistant and lightweight, has a different color and a higher melting point of about 660 °C (1,220 °F). Copper is notable for its excellent conductivity and reddish-brown color but does not exhibit the same level of corrosion resistance as zinc. Iron, on the other hand, is susceptible to corrosion and rusting, particularly when exposed to moisture without protective coatings, and has a higher melting point as well.
