There is a strange thing in the world, called Acid-Edta. Its nature is specific and it has a wide range of uses.

The nature of Acid-Edta is good for phase integration with various things. When it comes to metals, it can be combined with them. If it is attached to glue paint, it will form a new quality. Its quality is stable, and it is not afraid of ordinary temperature changes and moisture. And it is easily soluble in water, and if it dissolves, it will be scattered into particles, uniform and distributed, not sinking or floating.

As for its use, it is more common in engineering and medicine. Workers, the industry of metallurgy, rely on it to remove impurities. Among ores, there are many impurities, mixed between metals. If you put Acid-Edta in it, it will combine with hybridization, making the metal pure, of high quality and high price. And in dyeing and weaving, the color aid can be evenly attached to the fabric, and the color is bright and long-lasting. In the medical way, it can be used as a medicine guide. Some medicines, with the aid of Acid-Edta, can quickly enter the texture and cure diseases. And in the blood test, it can prevent blood from coagulating, so that the test results are certain.

The beauty of its reaction is also considerable. When it encounters alkali, it will neutralize and change, raw salt and water. In between processes, the heat will grow and fall, and its shape and color will be observed, and it will become aerated and liquid. When it encounters some organic matter, or opens a ring, or joins a chain, a new thing is formed, and the wonder of the change can be described without words.

If it is about its production, it is mined in the mines of mountains and rivers, and it has been worked through many ways. Grind it, refine it, transform it, remove its roughness, and take its essence. All kinds of processes need to be careful, and if there is a slight error, the quality will not be pure. Craftsmen work hard to obtain good products in the world for the use of all people.

The wonder of Acid - Edta is rare in the world when things change, they are widely used, and they are difficult to produce. Later generations should study it carefully, make good use of it, and make things do their best to benefit all people.
