Show an image or animation or description of what is happening when water dissolves NaCl.

Why is the freezing point lowered when salt is added to water?

The salt gets in the way of the water molecules, making it harder for them to move. When salt is added to water, it forms crystal molecules. They almost act as if they are in the way and block the area for it to freeze. As the temperature decreases, water molecules can attach and crystallize .
