1) Strong acid to weak acid: HCO4+NaCl=Naclo4+HCl 2) Difficult volatile acid to volatile acid: H2SO4+NaCl=NaHCO4+HCl
3) Take advantage of the difference in solubility: NH4HCO3+NACl=NH4Cl+NaHCO3
4) Nitric acid oxidation: 3NaCl + 4Hno3 = 3nano3 + NoCl + Cl2 + 2H2O
That's all I know.

The reaction between Na and NaCl solution is essentially the reaction between Na and H2O, 2Na + 2H2O = 2NaOH + H2, the phenomenon is: the sodium block floats on the water surface, reacts violently, melts into a bright ball, and swims rapidly.
Supplement: The sodium block is put into the NaCl solution and only reacts with water, while the sodium does not react with NaCl, and the NaOH formed by the reaction with water does not react with NaCl.

NaCl does not react with hydrochloric acid. That's because the two are mixed together and do not produce weak electrolytes, insoluble substances and volatile substances.
There are two principles to be paid attention to when writing chemical equations: first, it must be based on objective facts, and it is absolutely impossible to conjecture or fabricate substances and chemical reactions that do not actually exist; Second, to obey the law of conservation of mass, the types and numbers of atoms on both sides of the equal sign must be equal.
Chemical reaction: The process by which molecules break down into atoms, and the atoms rearrange and combine to form new substances, called chemical reactions. In the reaction, it is often accompanied by luminescence, heat, discoloration, and the formation of precipitate, etc., and the basis for judging whether a reaction is a chemical reaction is whether the reaction generates new substances.
Substance: It is the process by which old chemical bonds are broken and new chemical bonds are formed.
In the reaction, it is often accompanied by luminescence, heating, discoloration, and the formation of precipitates. The basis for determining whether a reaction is chemical is whether the reaction produces a new substance. According to the theory of chemical bonds, it can be judged whether a chemical reaction is based on whether there is the breaking of old bonds and the formation of new bonds in a change process.
Reaction phenomenon: exothermic, endothermic, luminous, discolored, precipitation, gas.
Reversible vs. Spontaneous Reactions:
Every chemical reaction is theoretically reversible. A positive reaction defines the conversion of a substance from a reactant into a product. The reverse reaction is the opposite, where the product is converted into reactants.
Chemical equilibrium refers to a state in which the positive and reverse reaction rates are equal, so that both reactants and products are present. However, the direction of the reaction in the equilibrium state can be changed by changing the reaction state, such as temperature or pressure. Le Chatre's principle is used here for product or reactant formation.
Although all reactions are reversible to some extent, some reactions can still be classified as irreversible. "Irreversible reaction" means "complete reaction". This means that almost all reactants form products, and even in extreme cases, the reaction is difficult to reverse.
Another reaction mechanism is called spontaneous reaction, which is a thermodynamic tendency that indicates that this reaction causes a net increase in overall entropy. Spontaneous reactions (as opposed to non-spontaneous reactions) occur without the need for external assistance (e.g., energy supply). In a chemically balanced system, the direction of the spontaneous reaction during the reaction can be expected to form more substances.
There are many categories in organic chemistry, including free radical reactions and ionic reactions; electrophilic reaction, nucleophilic reaction; Nitrification, halogenation, sulfonation, ammoniation, acylation, cyanidation, addition, elimination, substitution, polyaddition, polycondensation, etc.

Hello, it can't react because it can't produce gas or precipitation.

CLO - has strong oxidizing properties, whether in acidic, neutral, or alkaline environments. Especially in acidic environments, the oxidation of megatrousers is the strongest.
Since Cl2 has strong oxidizing properties, to oxidize Cl- to Cl2, Clo- must be done in an acidic environment, and the reaction is as follows:
clo- +cl- +2h+ =cl2↑ +h2o
Reaction: Cl2 + 2OH = Cl- +Cl- +H2O also indicates that Cl2 is more oxidizing than Cl- in an alkaline environment.
Reaction: Cl2 + H2O = Reversible = Cl- +Cl- +2H+ indicates that in a neutral environment, the oxidation of the two is comparable.
Summary]: NaCl does not react with Naclo, but after acidification, Cl- can oxidize Cl- to Cl2, and the centering reaction of the panicle code occurs.
clo- +cl- +2h+ =cl2↑ +h2o

Naclo is a salt in inorganic compounds, as well as sodium salt and citapochlorate. NACLO generally refers to sodium hypochlorite, which is the most common "chlorine" bleach in household washing. Other similar bleaching agents are potassium hypochlorite, lithium hypochlorite or calcium hypochlorite, sodium hypobromide or sodium hypoiodate, chlorine-containing oxide solutions, chlorinated trisodium phosphate, sodium or potassium trichloroisocyanurinate, etc., but are not usually used in household washing.
Bleaching is generally thought to be due to its strong oxidizing properties. Bleach is a variant that destroys the color system or produces a co-color group.
Generally speaking, if the solution temperature of sodium hydroxide is relatively high but has not yet reached 60 degrees Celsius, the total reaction equation that occurs will be the result of the sum of the indefinite ratio of the above two equations, the higher the temperature, the greater the proportion of the second equation, and vice versa.

NaCl: sodium chloride.
Catalog: Salts.
The main component of table salt.

The electronic formula of NaCl is Na+[Cl]-,There are two black dots in each of the four directions around Cl, a total of 8, representing 8 electrons.
Sodium chloride, chemical formula NaCl, colorless cubic crystalline or fine crystalline powder, salty taste. The appearance is white crystalline, and its ** is mainly seawater, which is the main component of table salt.
Physical properties: melting point 801, boiling point 1465, slightly soluble in ethanol, propanol, butane, miscible with butane becomes plasma, soluble in water, solubility in water is room temperature). Impure sodium chloride is deliquescent in air.
Industrial methods. It is introduced into the salt pan by seawater (with an average sodium chloride content), dried in the sun, and concentrated and crystallized to obtain a crude product. Seawater can also be heated by steam, filtered by sand filter, and concentrated by ion exchange membrane electrodialysis to obtain brine (containing sodium chloride 160 180g l) by evaporation to precipitate salt halide gypsum, centrifugal separation, and more than 95% sodium chloride (2% moisture) prepared by drying.
Rock salt and salt lake brine can also be used as raw materials, and the raw salt can be prepared by drying in the sun. When underground brine and well salt are used as raw materials, they are prepared by three-effect or four-effect evaporation and concentration, precipitation crystallization, and centrifugal separation.

The so-called sequential reaction is artificially determined for the convenience of understanding and calculation, while in the collision of microscopic particles, as long as the effective collision occurs, the reaction can occur, and it is not restricted by other ions, so it is a simultaneous reaction. >>>More
There was a chemical change.
A metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and held for a period of time, followed by a rapid cooling by immersion in a quenching medium. Commonly used quenching media are brine, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts that require surface wear resistance (such as gears, rolls, carburizing parts, etc.). >>>More
