Chlorine absorbed silicon

Moissan reasoned that if he were trying to liberate chlorine he would not choose a stable solid like sodium chloride, but a volatile compound like hydrochloric acid or phosphorus pentachloride. His preliminary experiments with silicon fluoride convinced him that this was a very stable compound, and that, if he should ever succeed in isolating fluorine, it would unite with silicon with incandescence, and that therefore he might use silicon in testing for the new halogen. After many unsuccessful attempts to electrolyze phosphorus trifluoride and arsenic trifluoride, and after four interruptions caused by serious poisoning, he finally obtained powdered arsenic at the cathode and some gas bubbles at the anode. However, before these fluorine bubbles could reach the surface, they were absorbed by the arsenic trifluoride to form pentafluoride (18, 23). 

If moderately strong x-rays emanated from the bones and teeth of this body or if radiation came from surrounding rocks or soil, then some of the x-rays would have been absorbed by elements at the surface of the body, such as sodium, silicon, phosphorus, sulfur, chlorine, potassium, and calcium, as well as carbon, oxygen, and nitrogen, and characteristic x-rays of relatively long wavelengths would be emitted due to an x-ray fluorescence effect. 

ACIDE CHLORHYDRIQUE (French) (7647-01-0) Hydrogen chloride gas is quickly absorbed in water, forming hydrochloric acid. Hydrochloric acid is a strong acid. Violent reaction with bases, strong oxidizers (with release of chlorine gas), acetic anhydride, cesium cyanotridecahydrodecaborate(2-), ethylidine difluoride, hexalithium disilicide, metal acetylides. sodium, silicon dioxide, tetraselenium tetranitride, and many organic materials. Incompatible with aliphatic amines, alkanolamines, alkylene oxides, aluminum, aluminum-titanium alloys, aromatic amines, amides, 2-aminoethanol, ammonia, ammonium hydroxide, calcium phosphide, chlorosulfonic acid, ethylene diamine, ethyleneimine, epichlorohydrin, isocyanates, metal acetylides, metal carbides, oleum, organic anhydrides, perchloric acid,...
