Acids that ionize completely are acids, while acids that do not ionize completely are acids.
Question
Acids that ionize completely are strong acids, while acids that do not ionize completely are weak acids.
Solution
Acids that ionize completely in solution are known as strong acids. These acids fully dissociate into their ions when dissolved in water, resulting in a high concentration of hydrogen ions (H⁺). Examples of strong acids include hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and nitric acid (HNO₃).
On the other hand, acids that do not ionize completely are termed weak acids. Weak acids only partially dissociate in solution, leading to a lower concentration of hydrogen ions compared to strong acids. Common examples of weak acids include acetic acid (CH₃COOH) and citric acid (C₆H₈O₇).
In summary, the distinction between strong and weak acids lies in their ability to ionize: strong acids dissociate completely, while weak acids dissociate only partially. This characteristic directly affects their reactivity, pH levels, and overall behavior in chemical reactions.
