strong acid

A strong acid is a substance that completely dissociates into its ions when dissolved in water. This means that it releases a high concentration of hydrogen ions (H⁺), which contribute to its acidic properties. Common examples of strong acids include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄). Due to their ability to fully ionize, strong acids can significantly lower the pH of a solution, making it highly acidic. They are often used in laboratories and industrial processes but can be corrosive and require careful handling.
