What precautions should be taken when storing standard solutions?
The choice depends on the properties of the chemical reagents: those that decompose easily when exposed to light should be stored in brown bottles, while alkaline solutions should be kept in plastic containers. It is also important to ensure that the storage temperature is not too high; if possible, install air conditioning to control the temperature.
This kind of question is very general. Some stable standard solutions can be stored for a long time in a regular laboratory environment. However, for some unstable standard solutions, it is necessary to take into account the effects of temperature, light, and ambient air, and to select an appropriate storage environment and shelf life.
