NaOH reacts chemically with carbon dioxide to produce something

Look at the proportion of the amount of matter between each other.

When CO2 is excessive.

naoh+co2=nahco3

When there is an overdose of alkali. 2naoh+co2=na2co3+h2oto pineryouyou:

Not at all.

Excess CO2 is an excess of carbonic acid, which produces the corresponding acid salts.

It is not a stable and unstable thing at all, but carbonic acid, hydrogen carbonate, ionization equilibrium and hydrolytic equilibrium between carbonate and hydrogen ions.

Sodium carbonate is alkaline, and CO2 is acidic when dissolved in water.

The first equation mentioned on the second floor is the equation in the process, because NaHCO3 is extremely unstable and easy to decompose, so as the amount of CO2 continues to increase, stable Na2CO3 will be generated in the endSo the final equation should be 2NaOH+CO2=Na2CO3+H2O

1.Excess sodium hydroxide: N(NaOH):N(CO2) 2:1, sodium carbonate is generated, and there is also excess sodium hydroxide.

n(CO2)=2:1, sodium carbonate is generated.

1 N(NaOH):N(CO2) 2:1, both sodium carbonate and sodium bicarbonate.

N(CO2) 1:1, the product is only sodium bicarbonate.

The reaction of carbon dioxide with sodium hydroxide will cause caustic soda to deteriorate, and the corresponding chemical reaction equation is: 2NaOH + CO = NA CO + H O. When a small amount of carbon dioxide reacts with sodium hydroxide, sodium bicarbonate and water are formed.

When there is an excess of carbon dioxide, carbon dioxide reacts with sodium hydroxide to form sodium bicarbonate: 2NaOH + CO2 = Na2CO3 + H2O, Na2CO3 + CO2 + H2O = 2NaHCO3, the total equation: NaOH + CO2 = NaHCO3.

Characteristics of sodium hydroxide solution

1. It should be noted that sodium hydroxide can be used as an alkaline cleaning agent in water treatment, soluble in ethanol and glycerin, insoluble in propanol and ether. It disproportionates with halogens such as chlorine, bromine, and iodine. It neutralizes with acids to form salt and water.

2. It should be noted that sodium hydroxide is easy to deliquescent in the air, so solid sodium hydroxide is often used as a desiccant. Liquid sodium hydroxide is not absorbent.

3. Detergent: Sodium hydroxide is used in the production of various detergents, and even today's laundry detergent (sodium dodecylbenzene sulfonate and other ingredients) is also made from a large amount of caustic soda, which is used to neutralize excess oleum after sulfonation reaction.

The equation for the reaction of sodium hydroxide and carbon dioxide is: 2NaOH+CO==NaCO+HO.

Sodium hydroxide has strong alkalinity and strong hygroscopicity, soluble in water, exothermic when dissolved, and the aqueous solution is alkaline and greasy; It is extremely corrosive and has a corrosive effect on fibers, glass, ceramics, etc.

Sodium hydroxide reacts with metal aluminum and zinc, non-metal boron and silicon to release hydrogen; It disproportionates with halogens such as chlorine, bromine, and iodine. It neutralizes with acids to form salt and water.

The reaction between sodium hydroxide solution and carbon dioxide is: sodium carbonate and water.

The reaction of sodium hydroxide with carbon dioxide does not belong to the four basic chemical inverse types (chemical reaction, decomposition reaction, displacement reaction, reintegration and spike decomposition reaction), nor does it belong to redox reaction. The chemical equation for the reaction between sodium hydroxide and carbon dioxide is: 2NaOH + CO2 = Na2CO3 + H2O, which belongs to the reaction of soluble alkali and acidic oxide Tongbu to form salt and water.

Sodium hydroxide

Sodium hydroxide, an inorganic compound, chemical formula NaOH, also known as caustic soda, caustic soda, solid soda, caustic soda, caustic soda. Sodium hydroxide has strong alkalinity and strong corrosiveness, and can be used as acid neutralizer, masking agent, precipitant, precipitation masking agent, chromogenic agent, saponifying agent, peeling agent, detergent, etc., and is widely used.

There are two methods for industrial production of sodium leakage in hydrogen and oxygen sheds: causticizing method and electrolysis method. The causticizing method is divided into soda ash causticizing method and trona causticizing method according to different raw materials; The electrolysis method can be divided into the separator electrolysis method and the ion exchange membrane method. Staff should take precautions, and if it accidentally touches ** and eyes, it should be rinsed with plenty of water immediately.

The working environment should have good ventilation conditions.

The inverse or code of sodium hydroxide and carbon dioxide should belong to the reaction between the alkali and non-metallic oxides, and do not belong to the four basic reaction types.

co₂+2naoh=na₂co₃+h₂o

It does not belong to any reaction type of sock dismantling.

Although the reactants are two compounds and the products are also two compounds, the reactants do not exchange components during the reaction, so they do not belong to the metathesis reaction.

The equation for the reaction of sodium hydroxide and carbon dioxide is:

2NaOH+CO ==NaCO+HO (the reaction when a small amount of carbon dioxide is introduced, is also a deliquescent reaction of sodium hydroxide solids).

Naoh+CO ==Na CO (reaction when excess carbon dioxide is introduced to sodium hydroxide).

The soda ash causticization method makes soda ash and lime into soda ash solution and lime milk by soda ash respectively, and carries out causticizing reaction at 99 101 °C, and the causticizing liquid is clarified and evaporated and concentrated to more than 40% to obtain liquid caustic soda, and the concentrate is further boiled and solidified to obtain a solid caustic soda product. Caustic sludge is washed with water, and the washing water is used to make alkali.

Depending on the amount of carbon dioxide, the product is different.

A small amount of carbon dioxide and sodium hydroxide form sodium carbonate and water, and excess carbon dioxide and sodium hydroxide form sodium bicarbonate. The equations are:

2naoh+co2=na2co3+h2o

naoh+co2==nahco3

The chemical equation of sodium hydroxide and carbon dioxide is.

1. A small amount of co:

2naoh + co₂ =na₂co₃ +h₂o

2. Overdose co:

naoh + co₂ =nahco₃

Relationship: Excess CO is equivalent to the CO of another molecule and reacts with the product NA CO in the first reaction formula (NA CO +CO +H O = 2NAHCO) to form NAHCO, which is the product of the second reaction formula.

First, the reaction of NaOH and CO is carried out to generate Na CO; If CO is excessive, the reaction of CO and Na CO is carried out. To remove CO, the amount of NAOH used should be excessive to ensure that CO is completely removed. When the NAOH is completely consumed, CO reacts with NA CO to form NAHCO.

In other words, while NAOH is still present, NAHCO cannot be generated.

Depending on the amount of carbon dioxide, the product is different.

1. A small amount of carbon dioxide and sodium hydroxide produce sodium carbonate and water.

2. Excess carbon dioxide and sodium hydroxide are suspected of being buried into bicarbonate and quarreling with sodium celery and touching ants.

3. Completely dried carbon dioxide does not react with sodium hydroxide.

Reasons why solid sodium hydroxide in the laboratory must be sealed and stored:

1. Absorb water vapor and deliquescent.

2. Absorb carbon dioxide and deteriorate.
