Sodium fire joke

When I was doing chemistry experiments in middle school, my teacher kept telling me about the dangers of sodium. As a result, a buddy risked his life to steal a mung bean-sized sodium and put it in his trouser pocket and took it away. ...

As a result, it rained heavily that day. ...

Reaction of sodium with water:

Add some water to the beaker, drop a few drops of phenolphthalein solution, and then put a small piece of sodium into the water. For safety reasons, beakers should be covered with glass sheets. The observed phenomenon and the conclusion drawn from it are: 1, sodium floats on the water surface (the density of sodium is smaller than that of water).

2. Sodium melts into a shiny ball (sodium reacts with water to release heat, and sodium has a low melting point).

3. Sodium swims around on the water (producing gas)

4. Make a hissing sound (generate gas and react violently)

5. The water dripping with phenolphthalein test solution in advance turns red (produces alkali).

Sodium will burn hydrogen because of this violent reaction, so the sodium fire cannot be put out with water, and it must be put out with dry sand.

2na+2H2O = 2NaOH+H2 ↑, the generated sodium hydroxide is highly corrosive. This guy is miserable enough.
