Acids

Acids are substances that release hydrogen ions (H⁺) when dissolved in water, making the solution acidic. They have a sour taste, can corrode metals, and turn blue litmus paper red. Common examples include hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and acetic acid (CH₃COOH). Acids are widely used in industries such as manufacturing, cleaning, food processing, and chemical production due to their reactive properties. They are essential in many chemical reactions and processes.
