Making Naphthalene Crystals
I realized that time passes so fast, it was about a week since I made a new post. I feel like it has been for only 3 days. Anyways, let’s get started with the post.
I’ll try to make Naphthalene crystals. Naphthalene is a white crystalline solid with a characteristic odor. It’s melting point is about 80°C. If you leave it to expose air, it’ll change into a gas.
I put about 7 balls of Naphthalene into a 600 ml beaker, and I put a flask with cold water on top of it.
The Naphthalene is vaporizing quickly. The vapors will get in contact with the cold water in the flask and turn back into a solid.
Crystals are also forming in the beaker, because it’s touching the cold air outside, just like what’s happening in the flask.
All of the Naphthalene has changed into liquid, it was boiling a little too fast so I stopped the heat.
The crystals are so fragile so I used a trash bag to make the crystals fall onto it.
Here are the crystals. They look like fern leaves and snowflakes! But I wish the crystals were chunks, not thin like this. I looked in the internet for pictures of Naphthalene crystals, and they’re just like mine. The reason that it’s yellow is because the light is just reflecting it.
Here’s the beaker:
