Acidic substances typically include compounds that can donate protons (H⁺ ions) in solution. Common examples are hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and citric acid, which often originate from organic or mineral sources. Acidic substances usually have a sour taste and can conduct electricity due to the presence of ions.
On the other hand, alkaline (or basic) substances are characterized by their ability to accept protons or donate hydroxide ions (OH⁻). Common examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), and ammonia (NH₃). Alkaline substances typically have a bitter taste and feel slippery when wet.
In general, acidic substances tend to be derived from non-metal oxides or organic compounds, while alkaline substances are usually metal hydroxides or carbonates.
