Barium hydroxide is mixed with many solutions of other metal salts. Reactions of barium hydroxide with ammonium salts are strongly endothermic. The reaction of barium hydroxide octahydrate with ammonium chloride or ammonium thiocyanate is often used as a classroom chemistry demonstration, producing temperatures cold enough to freeze water and enough water to dissolve the resulting mixture. Barium hydroxide presents the same hazards as other strong bases and as other water-soluble barium compounds: it is corrosive and toxic. Barium hydroxide Barium hydroxide is a chemical compound with the chemical formula Ba(OH)(HO). The monohydrate (x =1), known as baryta or baryta-water, is one of
Metallic dragon and adamantine dragons for brass and bronze, and released the latter dragons in a later book alongside cobalt, mercury, mithral, orium, and steel dragons. The classification of "metallic dragons" was used in the "Advanced Dungeons & Dragons" second edition "Monstrous Manual" (1993), although the gold(en) dragon first appeared in the original "Dungeons & Dragons" "white box" set (1974) and the other dragons comprising the category had been in print since the first edition "Monster Manual" (1977). The term was continued in use in the third edition and fourth edition "Monster Manual". Although weaker than many other varieties of dragonkind, brass
