hydrofluoric acid
Etches silicon dioxide
Hydrofluoric acid is a solution of hydrogen fluoride in water, used in industrial processes like etching glass and cleaning metals.
Unlike other strong acids, it penetrates skin and attacks bone, making it exceptionally dangerous even in dilute concentrations.
The lab required special protocols for handling hydrofluoric acid.
