Nowadays, acetic acid is mixed with solid phosphoric acid. Acetic acid is mild in nature and has an acidic taste, which is often found in food acylates. Phosphoric acid is in a solid state and has certain chemical properties.

When the two are mixed, at first, the liquid of acetic acid is moist, and the body of phosphorous acid gradually melts into it. The molecules of acetic acid and the particles of phosphorous acid approach each other, just like dancers on the dance floor, interlacing and interacting.

After a while, the color of the solution does not change, but the chemical reaction in it quietly takes place. The structure of phosphoric acid may change in the environment of acetic acid, and acetic acid may also be the medium for its reaction, which helps the rearrangement of molecules.

The direction of its reaction generates new compounds, or is a variant of acids, or has different chemical properties. This mixture, in the future or in the field of chemical industry, is used as a raw material to produce other substances; or in the field of scientific research, the sample is used to investigate the mystery of chemistry. It is endlessly changing and contains new opportunities.
