reactivity profile |
silver reacts violently with chlorine trifluoride (in the presence of carbon) [mellor 2 supp. 1 1956]. bromoazide explodes on contact with silver foil. acetylene forms an insoluble acetylide with silver [von schwartz 1918 p. 142 ]. when silver is treated with nitric acid in the presence of ethyl alcohol, silver fulminate, which can detonated may be formed. ethyleneimine forms explosive compounds with silver, hence silver solder should not be used to fabricate equipment for handling ethyleneimine. finely divided silver and strong solutions of hydrogen peroxide may explode [mellor 1:936 1946-47)]. incompatible with oxalic acid and tartaric acid [nav aer. 09-01-505 1956]. silver can form explosive salts with azidrine. ("ethyleneimine" brocure 125-521-65, midland (mich.), dow chemical co., 1965). ammonia forms explosive compounds with gold, mercury, or silver. (eggeman, tim. "ammonia" kirk-othmer encyclopedia of chemical technology. john wiley & sons, inc. 2001.). acetylene and ammonia can form explosive silver salts in contact with ag. (renner, hermann, gunther schlamp. “silver, silver compounds, and silver alloys." ullmann's encyclopedia of industrial chemistry. wiley-vch verlag gmbh & co. kgaa. 2001.) |
