In the matter of barium carbonate and acetic acid
Taste barium carbonate, encounter acetic acid. Barium carbonate has a heavy color and white matter, and a quiet nature. Acetic acid has a sour taste and a cold air, and is lively. The two meet each other, like a meeting of dragons and tigers.

Acetic acid, with its lively nature, wants to intersect with barium carbonate. Barium carbonate is still self-sustaining at first, but it cannot match the enthusiasm of acetic acid. The molecule of acetic acid surrounds barium carbonate, and with its acidic force, it gradually dissolves the structure of barium carbonate. The ions of barium carbonate then segregate in solution.

When barium carbonate encounters acetic acid, it converts into barium acetate, water and carbon dioxide. The barium acetate dissolves into the solution, clear and invisible. Carbon dioxide is like light smoke, escaping in the air and dis Water is a by-product of the combination of the two, and it fuses with the solution.

This change is not only a change of matter, but also a wonderful theory of chemistry. The acid of acetic acid and the base of barium carbonate merge to form a new substance. In the laboratory, you can see the effervescence of gas, the appearance of carbon dioxide escaping. The solution gradually clears, and barium acetate is hidden in it.

This chemical change can be used in industry and can be studied by academia. Make everyone understand the principle of the intersection of matter and the rule of change. Although invisible and colorless things meet and transform into phases, there is a wonderful image. This chemical charm is also.
