Barium bromide Barium bromide Barium bromide is the chemical compound with the formula BaBr. Like barium chloride, it dissolves well in water and is toxic in aqueous solution. BaBr crystallizes in a lead chloride motif, giving white orthorhombic crystals which are deliquescent. In aqueous solution BaBr behaves as a simple salt. Barium bromide reacts with the sulfate ion from sulfuric acid to produce a precipitate of barium sulfate. Similar reactions occur with oxalic acid, hydrofluoric acid, and phosphoric acid. Barium bromide can be prepared from barium sulfide or barium carbonate via reaction with hydrobromic acid to give hydrated barium bromide. This happens
Environmental impact of silver nanoparticles catalyzing chemical reactions, Raman imaging, and antimicrobial sterilization. Along with its antimicrobial properties, its low mammalian cell toxicity makes these particles a common addition to consumer products. Washing textiles embedded with silver nanoparticles results in the oxidation and transformation of metallic Ag into AgCl. Silver nanoparticles have different physicochemical characteristics from the free silver ion, Ag and possess increased optical, electromagnetic, and catalytic properties. Particles with one dimension of 100 nm or less can generate reactive oxygen species. Smaller particles less than 10 nm may pass through cellular membranes and accumulate within the cell. Silver nanoparticles were also found to
