Hello everyone. Today we are going to grow beautiful crystals of sulfur.
For this, we will need toluene and crystalline sulfur. Let’s take a flask and fill it with 10 grams of crushed sulfur.
Then we will need to pour about 100ml of toluene into the flask and turn the stove on to heat up our mix. When it is heated, our sulfur starts to dissolve in toluene.
Also, I have to tell you that this experiment should only be done in outdoors or inside a fume hood.
After the mixture reaches 95 degrees Celsius, all the sulfur will completely dissolve in toluene. Now let’s leave the mixture to cool down.
Upon reaching 55°C, yellow needle crystals of sulfur will begin to precipitate in the flask.
Also, if the mixture is heated again, the crystals will dissolve and the experiment can be repeated one more time.
