1. A bright yellow flame: The reaction of sodium with water is highly exothermic, meaning it releases a lot of heat. This heat is enough to ignite the hydrogen gas produced in the reaction, causing a bright yellow flame.
2. The sodium metal moving around the surface: Sodium is less dense than water, so it floats. As it reacts, the heat generated causes the sodium to melt, forming a small ball that moves erratically across the surface of the water.
Important Note: This is a dangerous experiment and should only be performed by trained professionals in a controlled environment.
