| At room temperature, sodium carbonate is an odorless, grayish-white powder which is hygroscopic. |
| In dry soils, a thin film of hygroscopic water is retained around individual soil particles. |
| On the other hand, SO 2 and chlorides have a corrosive action because water-soluble and hygroscopic salts are formed. |
| Gases and non-aqueous liquids can be dehydrated by passing them over or through a hygroscopic substance, one that readily absorbs water. |
| All phospholipids are hygroscopic and pick up water if they are not handled properly under inert gas atmosphere. |
| Fertilizers placed with the seed are hygroscopic and will draw moisture away from the seed. |
