Find the chemical equation for the reaction of acidic oxides with alkalis, urgently

The acidic oxide reacts with the basic oxide to form the salt CO2+MGO=MGCo3 acid oxide 1Reacts with water to form the corresponding acid: SO3+H2O=H2SO42

2.Reacts with alkali to form salt and water: CO2+2NaOH=Na2CO3+H2O.

3.Salt and water corresponding to alkaline oxides: CO2+MGO=MGC3 Basic oxides react with water to form the corresponding alkali CaO+H2O==Ca(OH) reacts with acids to form salt and water CaO+H2SO4==CaSO4+H2O reacts with acidic oxides to form salt MGO+CO2=MGO3

Acidic oxidesReacts with basic oxides to form salt Co +MGO=MgCo.

The common tarnene acid oxide has a dioxygen code for carbon.

CO, wide-hole nitrous pentoxide N O, sulfur trioxide.

SO, sulfur dioxide.

SO, heptachlorohydrideClO7, silicon dioxide.

SIO, etc., the ** oxides of transition group elements are generally acidic oxides. CO, NO, etc. are not acidic oxides or alkaline oxides, but are not salt oxides, and water is a special oxide.

Hydrate corresponding to acidic oxides.

It is an oxygenated acid, such as the hydrate corresponding to SO3 is H2SO4, the hydrate corresponding to CO2 is H2CO3, and the hydrate corresponding to SiO2 is H2SiO3, etc.

Most of the acidic oxides can be directly combined with water to form oxygenated acids, and a few acidic oxides (SiO2) cannot react directly with water. Acid oxides are generally prepared by direct oxidation of non-metals or thermal decomposition of oxygenated acids and oxytates.

Basic oxides + acid salts + water.

Iron oxide and dilute hydrochloric acid reaction: Fe O 6HCl = 2FeCl 3HO

Iron oxide and dilute sulfuric acid reaction: Tanyou Fe O 3H So Fe (SO) 3H O

The reaction of copper oxide and dilute hydrochloric acid makes CuO + 2HCl = CuCl2 + HO

Copper oxide and dilute sulfuric acid reaction: cuo + h so cuso h o

Magnesium oxide and dilute sulfuric acid reaction: MGO + H so Mgso H O

Calcium oxide and dilute hydrochloric acid reaction: Cao + 2HCl = CaCl HO

Note. Oxides that can react with acids are not necessarily basic oxides, such as SIO can react with HF, SIO is an acidic oxide, but not a basic oxide (it should be noted that SIO can react with HF is a characteristic of SIO, and it has nothing to do with whether it is a basic oxide or an acidic oxide).

Oxides of alkali metals are not necessarily basic oxides, such as Na O can react with water to form alkalis, but it is a peroxide and not a basic oxide. Because it has oxygen in addition to producing bases, it is not a basic oxide.

The chemical equation for the reaction of acidic oxides and bases is given below

1. Caustic soda deteriorates when exposed to air: 2NaOH + CO2 = = Na2CO3 + H2O

3. Caustic soda absorbs sulfur trioxide gas: 2NaOH + SO3 = = Na2SO4 + H2O

4. Slaked lime is deteriorated in the air: Ca(OH)2+CO2==CaCO3 H2O

5. Slaked lime absorbs sulfur dioxide: Ca(OH)2+SO2==CaSO3 H2O

Properties of acidic oxides.

1. Most of them can react with water to form corresponding acids (except for some oxides that cannot react with water, such as silica SiO2).

2. Reaction with alkali produces only one kind of salt and water.

3. Reaction with alkaline oxides.

Acidic oxides react with basic oxides to form salt CO+MGO=MGco.

Basic oxides are oxides that are dissolved in water and only form one type of alkali or react with acids to form only salts and water. Basic oxides are all oxides of metal elements, their alkalinity varies greatly, some (such as sodium, calcium, magnesium oxides) are easily combined with hydration and can quickly and completely neutralize with all acids.

Basic oxides must be metal oxides, while metal oxides are not necessarily basic oxides, such as Mn2O7 is an acid oxide, and Al2O3, BEO, Cr2O3, and Zno are amphoteric oxides.

The basic oxide can also react with the corresponding acid salt: Na2O + 2NaHSO4 = 2Na2SO4 + H2O

Of course, basic oxides can only theoretically be regarded as the products of the dehydration of the corresponding base, and not all basic oxides can react with water to form the corresponding base.

Chemical formulas of acidic oxides and bases: The writing of chemical formulas of the products of the reaction of acidic oxides with alkali solutions is a difficult point in the writing of chemical equations in this chapter, because such reactions are not metathesis reactions, and the chemical formulas of the products cannot be derived from the idea of "exchanging the components of the two reactants". How to overcome this difficulty?

Here are four ways to do this.

1.Law of Regularity. There are two laws in the reaction between acidic oxides and alkalis, one is that the reaction products are salt and water; Second, before and after the reaction, the valency of each element remains unchanged.

When writing the chemical formula of the product of the reaction between SO2 and NaOH, many students mistakenly write the result as "Na2O+S(OH)4" or "Na2SO4+H2O".The reason for the former mistake is that the first law is ignored, and the writing idea of the chemical formula of the products of the metathesis reaction is applied mechanically; The reason for the latter error is that the valency of S is not noticed that the valency of S is +4 before and after the reaction, and Na2SO3 is miswritten as the more common chemical formula Na2SO4

2.Imitation method. In the chapter on carbon, students have become familiar with the chemical equation of the reaction of carbon dioxide into clarified lime water:

co2+ca(oh)2==caco3↓+h2o.Using this reaction as a template, we can write the chemical formula of the product produced by the reaction of carbon dioxide with barium hydroxide and sodium hydroxide: BaCO3+H2O; na2co3+h2o.

3.Oxygen addition method. In junior high school chemistry, the most common acidic oxides are carbon dioxide, sulfur dioxide, sulfur trioxide, these acidic oxides react with alkali solution to form salts containing acid ions often contain one more oxygen atom than acidic oxides, therefore, in junior high school, we can "add oxygen" to determine the chemical formula of the salts generated by this kind of reaction.

For example, the chemical formula of the salt formed by the reaction of sodium hydroxide with carbon dioxide is Na2CO3 composed of Na and CO3 (CO2 becomes CO3 atomic cluster after adding one oxygen atom); The chemical formula of the salt formed by the reaction of sodium hydroxide with sulfur trioxide is Na2SO4 composed of Na and SO4 (SO3 becomes SO4 atomic cluster after adding one oxygen atom).

4.Step-by-step. The reaction of certain acidic oxides with alkaline solutions can be seen as occurring in steps:

The first step is the synthesis of acids by hydration of acidic oxides; The second step is the neutralization reaction between the acid and the alkali solution. For example, the reaction of sulfur dioxide with sodium hydroxide solution can be regarded as sulfur dioxide first synthesized with hydration to synthesize H2S03, and then H2S03 reacts with Xianyan NaOH to form Na2SO3 + H2O

It is worth mentioning that no matter what method is used to write the chemical formula of the acid collapsing oxide and the product of the reaction of the alkali, it is necessary to pay attention to the recall of the valency value of the relevant elements (atomic clusters) to prevent the written chemical formula from violating the rule that the algebraic sum of the positive and negative valency of the elements in the compound is equal to zero.
