What is the reason sodium reacts in water?
The metal reacts with water to form hydrogen Gas, the vigorous reaction causes the hydrogen to set fire; but WHY they react , is clearly to do with Ionic bonding, Metal+Non metals,
2 Na+ 2H2O = 2NaOH + H2 2H2 +O2 = 2H2O The second reaction is in there for a reason: Sodium reacts extremely violently with water. In fact, it creates a two-stage explosion. In the first stage, the sodium creates sodium hydroxide plus hydrogen and a LOT of heat. In the second, the hydrogen ignites to form water. The more sodium you use, the more reaction product you get and the bigger the explosion is.
Sodium is a group one metal which means it is highly reactive. If you have ever seen sodium placed into water you will see it goes off with a bang. The problemm with extracting sodium is water vapor in the air (humidity). Sodium will react with water extreamly easerly and quickly. For that reason it is hard to extract sodium as it reacts with the moisture in the air.
Sodium reacts exothermically with water. When it reacts small pea-sized pieces will bounce across the surface of the water until they are consumed by it, whereas large pieces will explode. While sodium reacts with water at room temperature, the sodium piece melts with the heat of the reaction to form a sphere, if the reacting sodium piece is large enough. The reaction with water produces very caustic sodium hydroxide and highly flammable hydrogen gas.
