Use ammonium bifluoride cream instead of hydrofluoric acid for acid etching. In solid [NH4][HF2], each ammonium cation is surrounded by four fluoride centers in a tetrahedron, with hydrogen-fluorine hydrogen bonds present between the hydrogen atoms of the ammonium ion and the fluorine atoms. This colourless salt is a glass-etchant and an intermediate in a once-contemplated route to hydrofluoric acid. 50mls add 5g APS. ), other physical and mechanical processes (heating, pouring, spraying, spills and evaporation from large If not breathing, give artificial respiration.
