An acid is a substance that donates hydrogen ions (H+) in a solution, resulting in a decrease in pH. Examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and citric acid (C6H8O7).
A base is a substance that accepts hydrogen ions (H+) in a solution, leading to an increase in pH. Examples of bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium carbonate (CaCO3).
