The Chemical Formulae of Acids: Strong and Weak Acids
Understanding the Basics of Acids
Acids are substances that donate hydrogen ions (H+) in a solution, resulting in a pH level lower than 7. They are classified into two main categories: strong acids and weak acids. Strong acids are those that completely dissociate in water, producing a high concentration of hydrogen ions, whereas weak acids only partially dissociate, resulting in a lower concentration of hydrogen ions.
The Importance of Chemical Formulae
The chemical formula of an acid is a representation of its molecular structure, indicating the number and type of atoms present in the molecule. In the context of the table provided, the chemical formulae of some acids are listed in the first column, and in the second column, it states whether each acid is strong or weak. The task at hand is to complete the table by listing the chemical formula of each species present at concentrations.
