Zinc Reacting with Sulfuric Acid
Zn + H2SO4 → ZnSO4 + H2
Tổng quan
Zinc reacts with dilute sulfuric acid to produce zinc sulfate and hydrogen gas. This is a straightforward single replacement reaction used in laboratory hydrogen generation. Zinc granules dissolve steadily with visible gas evolution.

Ví dụ thực tế
Zinc galvanization protects steel from corrosion partly because zinc preferentially reacts with environmental acids instead of the underlying iron.
Tầm quan trọng công nghiệp
Zinc sulfate is used in agriculture as a micronutrient supplement for crops, in the rayon manufacturing process, and in zinc electroplating baths.
