The Book of Mountains and Seas says: All things in the world contain wonderful qualities. In today's words, the genus of phosphorus includes phosphoric acid (Phosphoric Acid), phosphorous acid (Phosphorous Acid) and phosphate (Phosphate), and their properties and uses are unique.

Phosphoric acid is strongly acidic, and it is widely used in the field of chemical industry. It can be used to make fertilizers, nourish crops, and make whole grains abundant; it is also used in food processing to adjust taste and maintain quality. Its shape or liquid, clear and transparent, with strong natural properties, and should be used with caution.

Phosphoric acid is different from phosphoric acid. Although it is also acidic, its properties are slightly slower. In the process of chemical synthesis, it is often an important raw material, contributing to the formation of many delicate compounds. It can participate in reactions, change the structure of chemistry, and derive thousands of novel things.

As for phosphates, there are many kinds and different shapes. They are either found in ores or in living organisms. In industry, they can be used as additives to improve the properties of products; in the biological world, they are indispensable to life activities, related to the strength of bones and the transfer of energy.

Looking at these three, phosphoric acid, phosphite and phosphate, although they all belong to the family of phosphorus, they have their own characteristics and play different functions in the world. Either to benefit production or to benefit life, they are all wonderful existences in the world, just like the various miracles described in the Shanhaijing, waiting for the world to explore in depth, so as to make the best use of them and benefit everyone.
