rovoquent des précipitations en milieu métalliques generate precipitates in solutions containing metallic ions Explanation: That's what it means in Frenglish. This property is mentioned in wikipedia: In these analyses, heavy metal (and nonmetal) ions (e.g., Pb(II), Cu(II), Hg(II), As(III)) are precipitated from solution upon exposure to H2S. The components of the resulting precipitate redissolve with some selectivity, and are thus identified. -------------------------------------------------- Note added at 48 mins (2018-07-04 18:40:17 GMT) -------------------------------------------------- No idea what they're on about with 'esprits recteurs d'hydrogène sulfuré'. Probably black magic. -------------------------------------------------- Note added at 13 hrs (2018-07-05 07:00:57 GMT) -------------------------------------------------- The concept of "ion" definitely didn't exist in the XVIIth century. I don't have the slightest idea about how a "milieu métallique" was referred to at that time... https://en.wikipedia.org/wiki/Hydrogen_sulfide |
