Which acid should be stored in plastic containers rather than in glass ones?

Hydrofluoric acid should be stored in plastic containers rather than in glass ones.

Because of its strong reactivity towards glass and mild reactivity towards several metals, hydrogen fluoride (HF) ion is kept in plastic bottles.

Not all compounds may be safely stored in glass; for example, hydrofluoric acid can be kept in polymethylpentene, polyethylene, or Teflon containers despite being corrosive and not recommended for storage in glass.
