| Gases and non-aqueous liquids can be dehydrated by passing them over or through a hygroscopic substance, one that readily absorbs water. |
| Pyrophosphoric acid is colorless, odorless, hygroscopic and is soluble in water. |
| In dry soils, a thin film of hygroscopic water is retained around individual soil particles. |
| Salts are hygroscopic, meaning they absorb ambient humidity to keep the road surface moist and hold fine particles together. |
| Fertilizers placed with the seed are hygroscopic and will draw moisture away from the seed. |
| All phospholipids are hygroscopic and pick up water if they are not handled properly under inert gas atmosphere. |
