Strong acids are substances that completely dissociate into their ions when dissolved in water. This means they release a high concentration of hydrogen ions (H⁺), making the solution very acidic. Common examples of strong acids include hydrochloric acid, sulfuric acid, and nitric acid. These acids are often used in laboratories and industries due to their powerful reactivity. Because strong acids can be very corrosive, they must be handled with care. They can react violently with bases and certain metals, producing heat and sometimes dangerous gases. Understanding the properties of strong acids is essential for safe usage in chemical reactions and various applications.
