Remember that old high school chemistry experiment where salt crystals precipitate out of a saltwater solution—or maybe the one where rock candy crystals form from sugar water? It turns out that ...

A new theory 'demystifies' the crystallization process and shows that the material that crystallizes is the dominant component within a solution -- which is the solvent, not the solute. The theory ...

Students will be able to explain, on the molecular level, why water can dissolve salt. Students will be able to identify the variables in their experiment. Students will also be able to explain why a ...

Salt experiment. How and why does water mix in our oceans? ... dissolve it in water and you end up with a solution that is denser than water. Salt sinks so salty water is denser than pure water.

It's a simple experiment that is fun for all ages. Here's what you need: 1) A large plastic or glass jar 2) One cup of water at room temperature 3) 1/4 cup vegetable oil 4) Salt (rock salt works best) ...

The experiment is spraying microscopic salt particles into the air, and the secrecy surrounding its timing caught even some experts off guard. On supporting science journalism.
