Zinc Reacting with Sulfuric Acid
Zn + H2SO4 → ZnSO4 + H2
Обзор
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.

Пример из жизни
Zinc galvanization protects steel from corrosion partly because zinc preferentially reacts with environmental acids instead of the underlying iron.
Промышленное значение
Zinc sulfate is used in agriculture as a micronutrient supplement for crops, in the rayon manufacturing process, and in zinc electroplating baths.
