It is generally achieved by chemical additives.
It is usually mixed with baking soda and tartaric acid in water, covered and sealed, and shaken slightly.
You can also add baking soda ...... directly to the water
For example, homemade soda:
Ingredient formula (one bottle) baking soda grams citric acid (or tartaric acid) grams a little granulated sugar Juice to taste.
How to make Use a clean soda bottle, pour cold boiled water into the bottle, not too full, add some granulated sugar and a certain amount of juice. Then add grams of baking soda, and finally put grams of citric acid (or tartaric acid), immediately plug the mouth of the bottle with a stopper, and tie the stopper tightly with string or aluminum wire to prevent the soda from rushing out. Gently shake the bottle, a large number of bubbles will be generated in the bottle, and it will continue to tumble up and down, and it will be ready to drink after about 20 minutes.
If you sweat a lot, you can make salt soda instead of fruit juice soda, and the method is the same, just replace sugar and fruit juice with an appropriate amount of salt.
Just in case, it's best to wrap the soda bottle in a cloth when making soda.
How to make Baking soda and citric acid (or tartaric acid) are combined to produce a large amount of carbon dioxide, which is dissolved in water in large quantities under pressure. When drinking soda, the stomach and intestines do not absorb carbon dioxide, and carbon dioxide runs out of the mouth to take away a lot of heat, making people feel cool.

To correct this, reactions in aqueous (aqueous solution) do not necessarily have ions, but can also react between molecules.
Carbon dioxide. can be with water molecules.
reaction, which can also react with hydroxide:
co₂+h₂o = h₂co₃
co₂+oh⁻ =hco₃⁻
There is an ionization equilibrium in the solution:
h₂co₃ ⇌hco₃⁻+h⁺ ⇌co₃²⁻2h⁺
Specific reaction mechanism
The chemical formula of carbon dioxide is often written as "o=c=o", but in fact, there are two large bonds with three centers and four electrons in the molecule.
As shown below: <>
Due to oxygen electronegativity.
Stronger, in the carbon dioxide molecule, oxygen is negative, carbon is positive.
In the water molecule, oxygen is bonded with two hydrogens, respectively.
The remaining two unbonded electron pairs, again, are more electronegative due to oxygen, so oxygen in the water molecule is negativity and hydrogen is positive.
The oxygen in the water molecule and the carbon in the carbon dioxide molecule are attracted to each other and are close to each other, and the unbonded electron pairs of oxygen in the water molecule invade the bond of carbon, break one of the bonds, and squeeze the lone electron that originally belonged to carbon to the oxygen, causing the oxygen atom.
The negative valence causes the oxygen in the carbon dioxide to gain double electrons, and the oxygen in the water and the carbon in the carbon dioxide share the electron pairs of the original oxygen in the water to form bonds.
The hydrogen in the water undergoes atomic rearrangement and moves to the oxygen atom with a negative valence.
The reaction of hydroxide with carbon dioxide is similar, but since the hydroxide root itself has only one hydrogen, there is no hydrogen atom behind it.

Carbon dioxide is a covalent compound that does not release ions when dissolved into water. So carbon dioxide first reacts with water to form carbonic acid, which is an ionic compound that can be ionized in water to release hydrogen ions.
-
Carbon dioxide enters the water and reacts with the water to form carbonic acid. Carbonic acid ionizes to produce bicarbonate and hydrogen ions, and bicarbonate is further partially ionized.
-
No, not all of the water-soluble parts of carbon dioxide react. The specific reaction is the reaction between carbon dioxide and water, carbon dioxide participates in the reaction in the form of molecules, and carbon dioxide is dissolved in water before carbonic acid is formed, and then the carbonate and bicarbonate are ionized.

Carbon dioxide can react in one step to produce water, and there are two main categories:
Clause. 1. Carbon dioxide and hydrogen can react to produce water and carbon monoxide: H2 + CO2 = Co + H2O This reaction is reversible, and in fact, hydrogen reduces carbon dioxide has no practical value. In fact, water is used in industry to react with carbon monoxide to produce hydrogen and carbon dioxide.
This is a very important reaction in the ammonia synthesis process, which is called transformation. Coal and water react to get hydrogen and carbon monoxide: C+H2O=Co+H2Carbon monoxide and water react to get hydrogen and carbon dioxide:
CO+H2O=H2+CO2 hydrogen is used as a raw material for ammonia synthesis, and carbon dioxide is used to produce urea with liquid ammonia.
Clause. 2. Carbon dioxide can also react with alkalis to produce salts and water, such as carbon dioxide and calcium hydroxide: CO2 + Ca(OH)2 CaCO3 + H2O
-
Carbon dioxide and sodium hydroxide react to produce sodium carbonate and water.
-
It reacts with hydrogen to produce water and carbon monoxide, which is the method of preparing water gas.
-
1. At low temperatures, carbon dioxide gas is directly integrated into the water, and a certain pressure needs to be applied.
2. Use a compressed storage cylinder to trap carbon dioxide in water to dissolve it.
3. Use chemical additives to achieve it. Mix baking soda and tartaric acid into water, cover and shake.

There are two ways to incorporate as much carbon dioxide into the water as possible.
The first is to increase the pressure, just like the usual soda.
Carbon dioxide can generally be prepared by calcining limestone at high temperature or by the reaction of limestone and dilute hydrochloric acid, and is mainly used in refrigerating perishable food (solid), as a refrigerant (liquid), in the manufacture of carbonized soft drinks (gaseous) and as a solvent for homogeneous reaction (supercritical state). Regarding toxicity, studies have shown that low concentrations of carbon dioxide are not toxic, while high concentrations of carbon dioxide can poison animals.
-
Increased stress.
Increasing the pressure at room temperature increases the solubility of carbon dioxide in the water, allowing as much carbon dioxide as possible to be incorporated into the water.
For example, when the lid of beer is opened, a large amount of foam overflows because the carbon dioxide in the pressure is reduced.

Question 1: What substances are produced by carbon dioxide plus water under photosynthesis (1) Carbon dioxide plus water produces glucose plus water and oxygen under photosynthesis! (2) 6co2 + 6h2o ==c6h12o6 + 6o2
Question 2: What is the reaction of carbon dioxide to water? Carbon dioxide reacts with water to form carbonic acid, and the solution is acidic.
Question 3: Carbon dioxide and water, what does the reaction produce and oxygen? Carbon dioxide (CO2) and water (H2O) can only produce carbonic acid (H2CO3). Carbonic acid is unstable and easily recomposes into water and carbon dioxide on its own; But it is absolutely impossible to produce oxygen.
In high school, there are only two kinds of oxygen production next to liquid water: hydrogen peroxide is catalyzed by manganese dioxide, and water is electrolyzed.
I think you're asking about the water-gas reaction, where water drops onto burning coal, producing hydrogen, carbon monoxide, and carbon dioxide.
C+2H2O=(Reaction conditions: high temperature)2H2+CO2
C+H2O=(Reaction conditions: high temperature) H2+CO
The resulting gas rises and then comes into contact with oxygen for combustion. Therefore, the burning coal dripping with water will cause the flames to escape.
Question book does not rise four: what does water and carbon dioxide produce H2O+CO2=H2CO3 carbonic acid.
Question 5: Can carbon dioxide be converted to water Yes?
CO2 H2 (reversible, heating condition) H2O Co

Problem description: I heard the teacher say that carbon dioxide will react with water when it is dissolved in water, and some of it will only dissolve and will not participate in the reaction. Thank you.
Analysis: Your teacher's statement is not exact, but for the average middle school student, this is already fine. Carbon dioxide dissolves in water and undergoes the following reactions:
co2 + h2o ==h2co3
However, very little carbon dioxide actually participates in the reaction. Most of the carbon dioxide is in the form of hydrates, which may be formed by the association of CO2 with water through hydrogen bonding. The above reactions involve chemical equilibrium and are related to multi-lifetime factors such as temperature, partial pressure of carbon dioxide, carbonic acid concentration, etc.
The explanation of dissolution in middle school chemistry is very inadequate, and the role of solvation is not emphasized, in fact, solutes exist in the form of solvent complexes in solvents.
Similar to carbon dioxide, sulphur dioxide dissolves in water, and the reactions that occur are essentially limited to the formation of sulphur dioxide hydrates. Studies have shown that in the sulfur dioxide water-soluble hidden solution, a large amount of sulfur dioxide hydrate is present, and traces of HSO3 (-) are also seen, and the so-called sulfurous acid molecule is not detected at all, but because the solution is acidic, it is approximately called sulfurous acid.
The chemical formula of carbon dioxide is: CO2. A carbon dioxide molecule is composed of two oxygen atoms and one carbon atom through covalent bonds, and is a colorless and odorless gas at room temperature, with a greater density than air, soluble in water, does not support combustion, and reacts with water to form carbonic acid. >>>More
