Phosphoric acid and phosphoric acid, compared with
Phosphoric acid (Phosphoric Acid) and phosphoric acid (Phosphorous Acid), both of which are phosphorus-containing compounds, however, their properties are different.
As far as the chemical formula is concerned, the chemical formula of phosphoric acid is\ (H_ {3} PO_ {4}\), and the chemical formula of phosphoric acid is\ (H_ {3} PO_ {3}\). From the chemical formula, phosphoric acid is less than phosphoric acid, one oxygen atom.
Its acid is also different. Phosphoric acid is medium-strong acid, in aqueous solution, fractional ionization. The first step, ionization, equation is\ (H_ {3} PO_ {4}\ rightleftharpoons H ^{ + } + H_ {2} PO_ {4 }^{-}\) 。 However, although phosphoric acid is also an acid, its acidity is slightly stronger than that of phosphoric acid. Due to its structure, the connection between hydrogen atoms and phosphorus atoms and oxygen atoms is different, and its ionization is caused, and the energy of hydrogen ions is poor.
From the perspective of oxidation and reduction, phosphoric acid has strong reductivity. Because, among them, phosphorus, the element, has a valence of + 3, can rise, to + 5, such as, when reacting with a strong, oxidizing agent, can be oxidized. And, phosphoric acid, medium, phosphorus, the element, is + 5, has been, in, phosphorus, the element is more, higher valence, state, usually, oxidation, weak, reductive, very weak.
Uses are also different. Phosphoric acid is widely used in the manufacture of chemical fertilizers, such as calcium perphosphate, and other compound fertilizers. It is also used in food industries, such as cola, which can be used as a sour agent in beverages. Phosphoric acid is mostly used in chemical synthesis as a reducing agent, and can also be used in the preparation of special phosphorus pesticides.
In short, although phosphoric acid and phosphoric acid are only one word, they are different in many aspects, such as their properties, uses, etc., and they need to be detailed and identified in chemistry, research, industry, and life.
