Sentences with phrase «anhydrous ammonia»
Anhydrous ammonia is a chemical substance that is a form of ammonia without any water in it. It is commonly used in fertilizers to provide plants with nitrogen, an important nutrient for their growth. Anhydrous ammonia is also used in other industrial processes, such as refrigeration systems and pH control in water treatment. Full definition
