Definition & Meaning of Acids and Bases
Acids and bases are fundamental concepts in chemistry that describe substances with specific properties and behaviors in chemical reactions. An acid is typically characterized by its ability to donate protons (H+ ions) in a solution, while a base is defined by its ability to accept protons or donate hydroxide ions (OH-). The pH scale, ranging from zero to fourteen, measures the acidity or basicity of a solution, with values below seven indicating acidity and values above seven indicating basicity.
Common examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (HC2H3O2). Bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). Understanding these substances is essential for various applications in fields such as chemistry, biology, and environmental science.
How to Use Acids and Bases Worksheets
