Storage of Sodium Fluoride in Pyrex Bottles

Study Notes

Corrosion and Storage of NaF

NaF, or sodium fluoride, can corrode certain materials, particularly metals and some types of glass, which makes strategic storage essential.
Storage conditions must prevent exposure to light and moisture, minimizing the risk of chemical reactions and degradation.

Reasons for Dark Pyrex Bottles

NaF is stored in dark Pyrex bottles to protect it from photodegradation caused by light exposure that may affect its stability.
Dark glass prevents light from penetrating, preserving the integrity of NaF and ensuring its effectiveness for longer periods.

Recommended Storage Containers

Pyrex or similar borosilicate glass bottles are recommended for storing NaF due to their resistance to chemical corrosion and thermal shock.
These materials maintain structural integrity and minimize contamination or reaction with the stored substance.

Glass Susceptibility

The susceptibility of certain glass types to corrosion by NaF is attributed to the alkali nature of NaF, which can etch or degrade the glass surface over time.
Not all glasses are affected equally; specialized glass is necessary for the safe storage of alkali materials like NaF.

Benefits of Dark Pyrex Bottles

Using dark Pyrex bottles for NaF storage ensures maximum protection against light-induced chemical changes, thus extending shelf life.
These bottles also provide mechanical strength and resistance to temperature variations, critical for maintaining the quality of NaF.
