High school chemistry, the specific reaction of iron and copper in nitric acid.

Iron and dilute nitric acid reaction: Fe + 4Hno3 (dilute) = = Fe (No3) 3 + No + 2H2O

Iron will be passivated at room temperature when exposed to concentrated nitric acid, and the reaction when heated: Fe + 6Hno3 (concentrated) = = Fe (No3) 3 + 3 No2 + 3H2O

If Fe is excessive, the reaction with Fe(No3)3 continues: Fe + 2Fe(No3)3==3Fe(No3)2

3Cu + 8Hno3 (dilute) = = 3Cu (NO3) 2 + 2 No (gas) + 4H2O

Cu + 4 Hno3 (concentrated) = = Cu (No3) 2 + 2 No2 (gas) + 2H2O

Iron will be passivated at room temperature when exposed to concentrated nitric acid, and the reaction when heated: Fe + 6Hno3 (concentrated) = = Fe (No3) 3 + 3 No2 + 3H2O

If Fe is excessive, the reaction with Fe(No3)3 continues: Fe + 2Fe(No3)3==3Fe(No3)2

3Cu + 8Hno3 (dilute) = = 3Cu (NO3) 2 + 2 No (gas) + 4H2O

Cu + 4 Hno3 (concentrated) = = Cu (No3) 2 + 2 No2 (gas) + 2H2O

Excess nitric acid, all 3-valent iron, iron excess, bivalent iron, copper excess 2-valent iron, bivalent copper.

Category Discussion:1Excess nitric acid produces 3-valent iron ions and 2-valent copper ions, as well as the remaining nitric acid.

Equation: Fe + 4Hno3 (dilute) Fe (No3) 3 + No + 2H2O

3Cu + 8Hno3 (dilute) = = 3Cu (NO3) 2 + 2 No (gas) + 4H2O

2.If there is an excess of copper, the nitric acid is completely reacted, and the composition of iron ions depends on the amount of excess copper (if copper reacts 3-valent iron, the solution is 2-valent iron ions, and if there is only a small amount of excess copper, there are copper ions, 3-valent, 2-valent iron).

Equation: Fe + 4Hno3 (dilute) Fe (No3) 3 + No + 2H2O

3Cu + 8Hno3 (dilute) = = 3Cu (NO3) 2 + 2 No (gas) + 4H2O

2fe3+ +cu → 2fe2+ +cu2+

3.If there is an excess of iron, the nitric acid reaction is complete, and the excess iron reduces 3-valent iron ions, which should be an excess of iron, so there is no reaction between copper and nitric acid.

Equation: Fe + 4Hno3 (dilute) Fe (No3) 3 + No + 2H2O

fe + 2fe3+ →3fe2+

It should be that, there may be omissions, if you think that I'm here to help analyze Ha o( o

The chemical equation for the reaction of copper nitrate and iron: Fe+Cu(NO) Cu+Fe(NO).

Because the acidic conditions of hydrolysis are very weak, nitrate does not play an oxidizing role, it is just a displacement reaction.

Copper nitrate hydrate decomposes into copper oxide, nitrogen dioxide and oxygen at around 170°C

2cu(no₃)₂s) →2cuo(s) +4no₂(g) +o₂(g)

Nitric acid can be produced by thermally decomposing copper nitrate and introducing the resulting gas into water. The method is similar to the last step of the Oswa-method.

2cu(NO) 2cuo + 4NO+ O 3NO+ H o 2HNO+NOThe thin strips of wood impregnated with copper nitrate glow emerald green when exposed to flames, and magnesium nitrate produces an orange-green glow.

The chemical equation for the reaction of copper nitrate and iron: Fe+Cu(NO) Cu+Fe(NO).

Because the acidic conditions of hydrolysis are very weak, the nitrate cannot play an oxidizing role, and this Sun Zhaochun is a displacement reaction.

Copper nitrate hydrate decomposes into copper oxide, nitrogen dioxide and oxygen at around 170°C

2cu(no₃)₂s) →2cuo(s) +4no₂(g) +o₂(g)

Nitric acid can be produced by thermal decomposition of copper nitrate and chaining the resulting gas into water. The method is similar to the last step of the Oswa-method.

2cu(no₃)₂2cuo + 4no₂+ o₂

3no₂+ h₂o → 2hno₃+ no

Thin strips of wood impregnated with copper nitrate glow emerald green under flame, while magnesium nitrate produces an orange-green light resistant.

Yes, the chemical equation for the reaction of iron with copper nitrate.

It is Fe+Cu(NO) Fe(NO) Cu, because the acidic conditions of Na shirt hydrolysis are very weak, and the nitrate collapse difference cannot play an oxidizing role, which is just a displacement reaction.

Iron and copper nitrate undergo a displacement reaction because iron is more reactive than copper.

Iron and copper sulphate.

The phenomenon of anti-hole is that the surface of the iron layer precipitates a red substance, and the solution changes from blue to light green, and finally to brown.

Iron and copper nitrate react to form ferrous nitrate and copper.

Put a smooth iron wire in the blue copper nitrate solution, take it out after a few minutes, the surface of the iron wire will be covered with a layer of red copper, this reaction is the nuclear bucket roll replacement reaction, the iron replaces the copper nitrate pin burning solution.

If the red copper wire is immersed in ferrous nitrate solution, the copper wire will not change, indicating that copper cannot replace iron from ferrous nitrate solution, indicating that the chemical properties of iron are more active than copper.

The reaction equation between iron and copper nitrate is: Cu(NO3)2+Fe=Fe(NO3)2+Cu. Iron is a metallic element with atomic number 26 and an elemental iron chemical formula:

fe。Pure iron is white or silvery-white with a metallic luster. Melting point 1538, boiling point 2750, soluble in strong acid and medium strong acid, insoluble in water.

Iron has 0, +2, +3, +4, +5 and +6 valences, of which +2 and +3 are more common, and +4, +5 and +6 are rare.

Chemical formula Cu(NO3)2, white powder. It is easy to deliquescent, soluble in water, the solubility is 45g at 0, and concentrated nitric acid is added, which can be re-sunk. When red-hot, it decomposes into nitrogen oxides and copper oxides, which are decomposed by hydrochloric acid.

From the net result, it should be that Cu reacts with dilute nitric acid first.

Assuming that ferrous ions react with dilute nitric acid first to form dispersed ferric ions, then Cu reacts with ferric ions to form ferrous ions and copper ions, and the ferrous ions do not change, or they react with dilute nitric acid first.

So it is Cu that reacts with dilute nitric acid first.

Copper-iron mixture reacts with dilute nitric acid:

1.Mr. into ferrous ions; 2.After the iron reaction is completed, the reaction of copper; 3.After the copper reaction is completed, ferrous ions react with excess dilute nitric acid to form ferric ions.

This explanation should be more detailed), 5, (high school chemistry) copper-iron mixture reacts with dilute nitric acid Who reacts with dilute nitric acid first Copper or iron?

Mixture of divalent iron ions with copper who reacts first with dilute nitric acid why.

Copper nitrate and iron react to exothermic. The reaction equation of copper nitrate and iron is Fe+Cu(NO) Fe(NO)Cu. This reaction is a displacement reaction.

Because iron is more reactive than copper, the reaction can proceed spontaneously, so it is also an exothermic reaction.

Exothermic reaction in displacement reactionThe exothermic reaction in the displacement reaction includes the displacement reaction of metals and acids; displacement reactions of metals and salts; displacement reactions of aluminum and metal oxides; Displacement reaction of active metal and water.

Endothermic reaction in displacement reactionThe endothermic reactions in displacement reactions include the displacement reactions that occur with less reactive metals and water vapor; Most of the carbon and hydrogen to reduce metal oxides (a few such as carbon and hydrogen to reduce metal oxides are exothermic reactions); Displacement reaction of carbon and water vapor.

Displacement reaction in 2 casesSolid-state displacement: A solid-to-solid or solid-to-gas displacement reaction that occurs under heating or high temperature conditions.

Liquid displacementThe displacement reaction is carried out in an aqueous solution.

Refer to the above content: Encyclopedia - Displacement reaction

This is a displacement reaction, and all displacement reversals are redox reactions.

When an element and a compound react to produce another element and another compound, this reaction is called a displacement reaction. Because in the displacement reaction, the valency of the element will increase or decrease, and the electrons will be transferred or biased, so it is redox counterequilibrium. In addition, this reaction produces ferrous nitrate, not liquid iron nitrate, because copper nitrate is less oxidized under neutral conditions.

The order of metal activity is: potassium, calcium, sodium, magnesium, aluminum, manganese, zinc, chromium, iron, nickel, tin, lead, hydrogen, copper, mercury, silver, platinum, gold. The metal in front of the hydrogen can replace the hydrogen in the non-oxidizing acid, while the metal behind the hydrogen cannot replace the hydrogen in the acid.

Only the metals that are in front can be displaced, and the metals that are in the back, can be displaced.
