Formula:
The equivalent mass of an acid is calculated using the following fundamental formula:
Equivalent Mass (Acid) = Molar Mass (Acid) / Basicity (Acid)
Where:
- Molar Mass (Acid): Represents the mass of one mole of the acid, typically expressed in grams per mole (g/mol). This value can be found on chemical tables or calculated from the molecular formula.
- Basicity (Acid): Denotes the number of replaceable hydrogen ions (H+) per molecule of the acid. For instance, hydrochloric acid (HCl) has a basicity of 1, sulfuric acid (H2SO4) has a basicity of 2, and phosphoric acid (H3PO4) has a basicity of 3.
