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

2. Why is the freezing point lowered when salt is added to water?
2. The freezing point is lowered when salt is added to water because, when the salt is added to the water the molecules take the salt crystals and spread them apart. Then, it takes longer for the ice to freeze because, the water molecules are changed with salt added to them. Salt has a lower freezing point, therefore it takes a short time for salt water to freeze than for instance, water.
