Whether chemical reagents deteriorate during storage depends on both internal and external factors. The internal factor is the physical and chemical properties determined by the reagent's own chemical structure, while the external factor is the environmental conditions in which the reagent is stored.
To ensure proper storage, it is essential to understand the relationship between the reagent's structure and its properties, and to create an external environment suitable for reagent storage.
Reasons for Chemical Reagent Deterioration
The environment mainly refers to storage temperature, light exposure, and the medium. The medium generally refers to air and any impurities mixed in. In addition to the oxygen, carbon dioxide, and water vapor present in the air, the storage room often contains vapors from various volatile reagents that have diffused into the air. Common examples include hydrogen chloride, nitric acid, hydrogen sulfide, sulfur dioxide, bromine, iodine, ethylene, formaldehyde, and other vapors. Additionally, there are dust particles floating in the air, which may include inorganic substances, organic substances, and various microorganisms.
Under certain conditions of temperature, light, and medium, chemical reagents will gradually change and eventually deteriorate. This process involves both physical changes and chemical changes. The former leads to loss of chemical reagents, while the latter can cause complete deterioration and failure of the reagents.
