Hydrofluoric Acid Solutions Cannot Be Stored In Glass Containers Because Hf Reacts

Contents

Hydrofluoric acid, HF(aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq). This measurement is used because it's more meaningful in nonaqueous systems, like those found in organic chemistry. 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. permalinkembedsaveparentgive gold[+]SCredditor comment score below threshold-7 points-6 points-5 points 5 years ago(0 children)EHHHHHHHHHHHHHHHHHHHH |FTFY They don't speak Zerg round these parts ¯_(ツ)_/¯ permalinkembedsaveparentgive gold[–]MershedPerderder 0 points1 point2 points 5 years ago(2 children)Will radiation "seep" through
