Hydrofluoric acid is one of the most dangerous acids known. It needs to be treated differently then even strong acids like sulphuric and hydrochloric.

Reason why Hydrofluoric acid is not kept in glass bottles:
Reaction with Silicon Dioxide:
- Hydrofluoric acid reacts with the silicon dioxide present in glass bottles.
- This reaction forms silicon tetrafluoride and water.
- Silicon tetrafluoride is a gas that can cause the glass to weaken and eventually break.
Consequences of the reaction:
- The reaction between hydrofluoric acid and silicon dioxide weakens the glass structure.
- This can lead to leakage of the acid and potential hazards to the surrounding environment.
- Moreover, the glass bottle may break unexpectedly, causing spills and exposure to the corrosive acid.
Alternative storage materials:
- Due to the reactivity of hydrofluoric acid with glass, it is commonly stored in containers made of materials such as Teflon or polyethylene.
- These materials are resistant to the corrosive nature of hydrofluoric acid and do not react with it, ensuring safe storage of the acid.
