Properties of Matter

Fun Facts

  • Salt does not dissolve in acetone.
  • Acetone is a chemical found in nail polish remover to dissolve nail polish.
  • Styrofoam is not dissolved by water.

Why Do We Need To Know About Solubility

Studying solubility helps us know how different things mix and why we use certain materials for some jobs. For example, acetone can’t dissolve salt, but it can dissolve nail polish. This shows how important solubility is in making and removing products in the beauty industry.

This idea is also key in engineering, storing chemicals, and making things. Knowing what materials can mix helps choose the right materials for safety and to make sure things work right. Picking a container that’s not made of Styrofoam for storing acetone to avoid chemical accidents shows how solubility helps us make smart choices in many areas.

Frequently Asked Questions

Which property did Zoe use to figure out which metal was sodium and which was iron?
Zoe knew that iron is magnetic and sodium is not so she tested each with a magnet.
What property of sodium metal did you observe?
Sodium metal reacts with water causing an explosion.
Which is more dense: sulfur hexafluoride or helium? How do you know (what evidence did you see)?
Sulfur hexafluoride is more dense than air. When placed inside a balloon, the balloon falls to the ground. Helium is less dense than air. A helium-filled balloon floats in air. A boat filled with air floats on top of Sulfur hexafluoride gas.
