Question

Why fluorine can't be kept in glass container?

Answer 1

HF can react with glass, so it doesn't work there. ... Thus, HF is stored in plastic containers (I have seen HF bottles), which are mainly organic compounds which contain few, if any, ionic bonds which would be affected by HF. Also, HF, due to the small molecule size can penetrate through human skin, and is very poisonous.

Answer 2

chlorine as disinfectant for water - Lenntech Concentrated hydrochloric acid can even corrode stainless steel. This is why it is stored either in glass or in plastic. Chlorine is a very reactive and corrosive gas. When it is transported, stored or used, safety precautions must be taken.
