The pulp is also ginger. The acetic acid of ginger, its main use, is both seasoning and medicine.
In the way of seasoning, the acetic acid of ginger has the ability to increase the fragrance and remove the fishy smell. When cooking fish, the fish has a fishy smell. Adding ginger and acetic acid of ginger can remove its fishy smell and increase the fresh fragrance of the fish. Another example is stewing meat, ginger acetic acid can solve the greasy meat, make the meat taste mellow and fragrant. In cold dishes, ginger acetic acid can improve the taste, make the taste of the dish richer, stimulate the appetite, and make the index finger move.
As for medicine, ginger acetic acid also contributes. "Compendium of Materia Medica" says: "Ginger, spicy, lukewarm, non-toxic. Take it for a long time to remove the odor and channel the gods. "Ginger's acetic acid is warm, with the effect of warming and dissipating cold. If people occasionally feel cold, cold and fever, drinking ginger soup can help sweat and relieve the surface, and dispel the evil of wind and cold. Those with spleen and stomach deficiency, often eat things containing ginger's acetic acid, which can warm the spleen and stomach, improve digestion, relieve epigastric cold pain, vomit and water. And ginger's acetic acid can promote blood circulation, make qi and blood flow smoothly, and also has the effect of auxiliary treatment for diseases caused by cold coagulation and blood stasis.
Therefore, ginger's acetic acid, when used in diet seasoning, can add the beauty of delicious food; when used in medicine and health, it can cure diseases and keep fit. It is actually a good product with a wide range of uses.

Mercury is a metallic element, and its corresponding carbonate is mercury carbonate. Mercury has many unique physical properties.
Mercury is in a liquid state at room temperature and pressure, which is one of its remarkable characteristics. Generally, metals are mostly solid, while mercury exists in a liquid state at room temperature alone, like a smart silver liquid. It is very mobile and can roll freely on a plane, and its shape changes with the carrier.
Its color is silver white, with a dazzling luster, just like a silver mirror reflecting light, shining under the light, showing the brilliance of the metal.
Mercury has a high density, reaching 13.59 grams/cubic centimeter. Compared with common metals, such as 7.87 grams/cubic centimeter of iron, mercury is heavier. If you weigh the same volume of mercury and other metals in your hand, you can clearly perceive the heavy texture of mercury.
In addition, the melting point of mercury is very low, only -38.87 ° C, which allows it to maintain a liquid state in a low temperature environment. The boiling point is relatively high, 356.6 ° C, which means that a higher temperature is required to make it boil into a gaseous state.
In addition, mercury has good electrical conductivity, although it is not the first among all metals, but it can also play a corresponding role in circuit conduction and other aspects, and has certain applications in the field of electronics. And the surface tension of mercury is large. On a clean plane, mercury droplets will naturally shrink into a nearly perfect spherical shape, just like round silver beads. This phenomenon is a manifestation of surface tension.

Carbonic acid in rivers has various chemical properties.
Carbonic acid has acidic characteristics. When encountering litmus test solution, it can be turned from purple to red, which is a clear proof of its acidity. In water, carbonic acid can be separated and dissolved, releasing hydrogen ions, which is the source of its acidity.
Carbonic acid is also unstable. A little heat, it is easy to decompose into water and carbon dioxide. With a liquid of carbonic acid at a slight temperature, bubbles can be seen escaping, which is carbon dioxide. The image of its decomposition is like a changing situation, which changes in an instant.
Carbonic acid can combine with bases. If it encounters bases such as sodium hydroxide, it will neutralize and produce corresponding salts and water. This reaction is similar to the harmony of yin and yang, and the ebb and flow of each other, returning to equilibrium.
Furthermore, carbonic acid can react with certain salts. In the case of calcium carbonate, under certain circumstances, calcium bicarbonate can be formed. This change is like the circulation of the universe, and new things are born.
Carbonic acid also has its wonderful effect in nature. In rivers, carbonic acid interacts with rocks and minerals, which has a great impact on geological changes and the shaping of landforms.
Carbonic acid in the field of chemistry, with its unique properties, deduces many magical reactions, just like the subtle rhythm between heaven and earth, which attracts people to explore the hidden secrets.

The acid of the Fuhe River, there are various ways to make it. First, you can use alkali to sum it up. The ancient wise men knew that alkali and acid can be phased. If you get plant ash, it contains alkali, dissolves in water, and pours it in the acid river. When alkali and acid meet, it will cause a neutralization change, the acid will gradually disappear, and the water can be leveled.
Second, you can lead other water to dilute it. Looking at the Fuhe River, the water potential converges, and its nature gradually changes. If you lead the water of the Qingchuan River into the acid river, the acid water will be divided into many waters, and the concentration of acid will drop. Find a source of water with vast and pure quality, dig a canal to divert flow, and lead it into the river, so that the acid gas will be slightly reduced, and the water quality may be improved.
Third, plant something that absorbs acid on the riverbank. There are plants and trees in the world that can absorb acid in the body and turn it into useful. Choose such plants and trees, which are widely planted on both sides of the river, and their roots enter the soil, or they can absorb the acid in the river. Over time, the acidity of the river becomes lighter. Such as calamus, which likes water and dampness, or can grow on the banks of the acid river, which can absorb pollution and absorb filth, or it also has an effect on acid; or reeds, which are clustered on the waterfront and have a well-developed root system, or they can be selected for acid absorption.
Fourth, filter it with stones. Choose the ones with mild quality, pile them in the river, and let the water pass through them. The culture of the stone may retain acid, and the water will filter out. For example, limestone, although not purely designed to remove acid, is effective in the filtration of water, or it can be tried. The softstone becomes a dike, the water flows between the stones, the acid gas may remain in the stone, and the clear water flows down.
All these numbers can be cited by the ancients in the treatment of water, but they should be done with caution, observe its effect and adjust it, and only then can good results be obtained.

Hearing what you are inquiring about, it is the price range of Jiang's acetic acid in the market. However, if you want to determine its price, you need to consider the time, place and various reasons in detail.
In normal times, acetic acid in the city, if its quality is excellent, the price may be slightly higher; if it is of average quality, the price is appropriate. And when times are different, the price is also different. When the goods are abundant, the price may be stable and slightly reduced; when the goods are scarce, the price may be raised.
And its price varies depending on the place of sale. In the capital of the big port, the business is fierce, and the price may be leveled; in remote places, it is difficult to transport goods, and the price may increase.
According to common sense, Jiang's acetic acid, of high quality, is worth two or three silver per catty; of medium quality, one tael to two taels; of average quality, or a few to one taels. However, this is only an idea, and the actual price must be determined according to the current market conditions, supply and demand. Changes in the city are instantaneous. If you want to know the exact price, you should go to the city in person and ask the merchants to get the true meaning.
