This is a picture of salt water. Salt is hydrophilic. Hydrophilic items are things that can be dissolved in water. Salt is a hydrophilic substance that can even attract water out of the air. It is useful in food to draw some of the water out. The hydrophilic molecules not only dissolve in water but other polar substances as well. Other examples of hydrophilic substances are sugar, chlorine, and alcohol.
