硫酸suān是一種最活潑的二元無機強酸，能和許多金屬發生反應yīng。高濃度的硫酸有強烈吸水性xìng，可用作脫水劑jì，碳化木材cái、紙張zhāng、棉麻織物及生物皮肉等含碳水化合物的物質zhì。與水混合時shí，亦會放出大量熱能néng。其具有強烈的腐蝕性xìng和氧化性，故需謹慎使用yòng。是一種重要的工業原料liào，可用於製造肥料liào、藥物wù、炸藥yào、顏料liào、洗滌劑jì、蓄電池等děng，也廣泛應用於淨化石油yóu、金屬冶煉以及染料等工業中zhōng。常用作化學試劑jì，在有機合成中可用作脫水劑jì和磺化劑。

Sulfuric acid is one of the most active binary inorganic strong acids, which can react with many metals. High concentration sulfuric acid has strong water absorption and can be used as dehydrating agent, carbohydrate-containing substances such as carbonized wood, paper, cotton and linen fabrics and biological skin and meat. When mixed with water, a large amount of heat is released. It has strong corrosiveness and oxidation, so it should be used cautiously. As an important industrial raw material, it can be used in the manufacture of fertilizers, drugs, explosives, pigments, detergents, batteries, etc. It is also widely used in the purification of petroleum, metal smelting and dyestuff industries. It is often used as a chemical reagent, dehydrating agent and sulfonating agent in organic synthesis.
