Endothermic Reactions Demonstration

 · Solid barium hydroxide reacted with solid ammonium thiocyanate produces barium thiocyanate, ammonia gas, and liquid water. This reaction gets down to -20°C or -30°C, which is more than cold enough to freeze water. It''s also cold enough to give you frostbite, so be careful! The reaction proceeds according to the following equation:

Barium Hydroxide

Barium hydroxide has the molecular formula of Ba (OH)2 and the molecular weight of 121.6324 g/mol. It occurs as an anhydrate whose prismatic, colorless crystals are very deliquescent. Barium hydroxide can be prepared by dissolving barium oxide (BaO) in water: BaO + 9H2O ⇒ Ba (OH)2·8H2O.

Barium Swallow (Precare)

 · Healthcare providers will take x-rays while you stand, before you drink the barium. In a single contrast barium swallow, you will drink up to 2 large barium mixtures. In a double contrast barium swallow, you will first drink a mixture of baking soda and an anti-foam agent. These substances produce gas to help expand your stomach and bowel.
