Activity 4 1-19-11 Dissolving

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?
Adding salt to water lowers the freezing point significantly. Water saturated with salt--holding as much salt as it can--has a freezing point of -21 degrees Celsius or -6 degrees Fahrenheit. For the most part, you can add anything to water and it will lower its freezing point.
