WATER & SODIUM EXPERIMENT First off, the observations include: A very hot exothermic reaction, the sodium constantly moving in warm water, the water surrounding the Na turned a shade of pink, the sodium eventually caught on fire, and It still moved rapidly after it caught on fire (it looked like a spinning top that glowed a bright pink). After catching on fire it exploded into a blaze of pink flames. The sodium was destroyed into microscopic, burnt specs. • Na + H2O= H2 + Energy = BOOM!!! This is the chemical equation of what happened. The materials I used are Na (a.k.a. Sodium), H2O (a.k.a. Fresh Water), a 20 inch plastic bucket (new), and special gloves to hold the sodium (rubber). Sodium is an alkaline metal and is therefore unstable when contact is made with water. I also want to include what we learned. We learned that alkali metals are very reactive with water after causing a small explosion. We also learned that enormous amount of energy is produced, which caused the explosion. Another spec of knowledge obtained from this is that heat caused the enormous amounts of energy produced. Though the most important thing we learned is to just not buy metallic sodium because of the enormous amount of precautions needed to store it. I would also say that this project should be done under adult supervision even though there was none during our experiment. The procedure taken is on the separate paper attached to this one.
