H₂SO₄, commonly known as sulfuric acid, is a strong mineral acid composed of sulfur, oxygen, and hydrogen. It is a colorless, oily liquid that is highly corrosive and can cause severe burns. Sulfuric acid is widely used in various industries, including the production of fertilizers, petroleum refining, and chemical manufacturing. This acid is also a key component in lead-acid batteries, which are commonly found in vehicles. Due to its strong dehydrating properties, H₂SO₄ can remove water from substances, making it useful in many chemical reactions. Proper safety measures are essential when handling this hazardous material.
