Hello everyone. Today we will conduct various reactions with the metallic sodium. I finally managed [to] buy it.
So I expect this video to be quite interesting as you can see sodium is stored in Kerosene inside jar.
We need to take a piece of sodium and put it on a filter paper to absorb the remaining kerosene.
First I will tell you about the physical properties of sodium metal.
Density of sodium is almost the same as water melting point being [97] degrees Celsius.
Sodium is a quite soft metal and can be easily cut with a knife.
Hardness of sodium is almost identical to an eraser that you use in schools [it] requires the same
afford to cut it, on the cut edge you can see the shiny surface of sodium.
However being in the air it oxidizes rather quickly and cover with a layer of peroxides and carbonates.
Now let's talk about the most interesting moment the chemical properties [of] sodium. Sodium reacts with water.
Take a small piece of sodium and put it in water.
By the way the indicator phenolphthalein was added in the water.
As a result [of] reaction of sodium with water
sodium hydroxide and hydrogen are formed. From the heat of the reaction the sodium melts and turns
into a sphere. It is mostly safe to conduct experiments with small pieces of sodium as they are the most controllable.
Very large pieces of sodium ignite spontaneously, and explode when the reacting with water, so that is very dangerous.
Now, let's see the reaction of sodium with ethanol. Put a piece of sodium in ethanol.
As you can see the reaction is quite slow.
Moving to the next reaction.
The interaction of sodium is hot glycerol.
It is poured into the beaker and let's add there a piece of sodium metal.
Sodium immediately melts and lights up in our hot glycerol.
this produce hydrogen and sodium glycerate.
Next let's view the reaction of sodium with 30 percent acetic acid.
First sodium lights up and then the reaction proceeds the same way as it does with water.
Now moving to [the] reaction of sodium is 30% hydrogen peroxide. This reaction again is very dangerous.
Because sodium ignites and explodes.
Next the reaction of sodium and sulfur. I have poured a little bit of sulfur on the stove and
now I'm adding the pieces of sodium.
To start the reaction it was moisten the sodium, for this I have used a wet piece of stick.
As well to all that, [I] quite like the behavior of sodium on the wet grass if you put sodium on the wet grass
It ignites and starts to burn.
The product of this reaction is sodium peroxide
Finally, I just can't resist and decide to throw
approximately 15 grams of sodium in a large puddle don't repeat that experiment by yourself because it's very dangerous.
