Arrhenius acid

An Arrhenius acid is a substance that increases the concentration of hydrogen ions (H⁺) in water when dissolved. This characteristic causes the solution to become more acidic. Common examples include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄). The Arrhenius theory helps to explain how acids behave in chemical reactions, particularly how they can react with bases to form water and salts. Understanding Arrhenius acids is fundamental in fields like chemistry, biochemistry, and environmental science, as they play significant roles in various processes and reactions.
