The chemical equation for the reaction of nitric acid and alumina

Equation. It can only react with dilute nitric acid, not concentrated nitric acid).

Alumina is available in two configurations, -Al2O3 and -Al2O3. -Al2O3 is very stable and is a colorless orthorhombic crystal with a melting point of 2015 °C and a boiling point of 2980 °C. It is insoluble in water, concentrated acid and concentrated alkali, and has the properties of atomic crystals, so the alumina of this configuration cannot react with concentrated nitric acid.

Nitric acid is a strong acid with strong oxidizing and corrosive properties.

It belongs to the monologic inorganic strong acid and is one of the six inorganic strong acids.

6hno3+al2o3⇔2al(no3)3+3h2o。

Nitric acid is a strong acid with strong oxidizing and corrosive properties, which is a monary inorganic strong acid and an important chemical raw material. It can be used in industry to make fertilizers, pesticides, explosives, dyes, salts, etc.; In organic chemistry, the mixture of concentrated nitric acid and concentrated sulfuric acid is an important nitrification reagent, and its aqueous solution is commonly known as nitrate water or sulfuric acid. The hazard symbols are O (Oxidizing Agent) and C (Corrosive).

The anhydride of nitric acid is nitrous pentoxide (N O5).

Alumina (ALO) is a compound with a high hardness of 2054 and a boiling point of 2980, which is an ionic crystal that can be ionized at high temperatures and is often used in the manufacture of refractory materials. Industrial Al2O3 is prepared from bauxite (Al2O3 3H2O) and diaspore, and for Al2O3 with high purity requirements, it is generally prepared by chemical methods.

Al2O3 has many homogeneous crystals, and there are more than 10 known at present, and there are mainly 3 crystal forms, namely -Al2O3, -Al2O3, and -Al2O3 (corundum). Among them, the structure is different and the properties are also different, and it is almost completely converted to -Al2O3 at high temperatures above 1300.

2al+3cu (no3)2═2al(no3)3+3cu。

Aluminum put copper nitrate.

Aluminum nitrate and copper are formed in solution, and the chemical equation of the reaction.

is: 2al+3cu (no3)2 2al(no3)3+3cu; This reaction is a reaction in which an element reacts with one compound to produce another element and another compound, which is a displacement reaction.

Because aluminum belongs to the active metal, in the metal activity order table.

The aluminium element is placed in front of the copper element, so the elemental aluminum can replace the copper from the salt solution of copper. The reaction phenomenon is that a layer of red copper-copper will appear on the surface of the aluminum, and the solution will gradually change from blue to light, and finally become colorless.

The use of aluminum is fiercely judged

Aluminum combustion in oxygen can emit a lot of heat and dazzling light, and is often used in the manufacture of ** mixtures, such as ammonium aluminum explosives (the skin is made of aluminum powder, ammonium nitrate.

charcoal powder, smoke black and other flammable organic substances), combustion mixtures (e.g., with thermite.

Bombs and shells can be used to attack hard-to-fire targets or tanks, artillery, etc.) and lighting mixtures (e.g., 28% aluminium powder, 68% barium nitrate, and shellac).

Aluminum powder has a silver-white luster (the color of the general metal is mostly black when it is powdered), and it is often used as coatings, commonly known as silver powder and silver paint, to protect iron products from corrosion, and beautiful.

Alumina. Ionic equation with hydrochloric acid.

al2o3+6h+=2al3++3h2o。

Parenchymal Al2O3 is reacting with H+. Trillion dressed up.

The first step is to write the chemical equation.

Then disassemble HCL and ALCL3 respectively, H2O and Al2O3 can not be disassembled, and then remove the same left and right sides to obtain.

The chemical equation of the reaction between alumina and hydrochloric acid is: AlO +6HCl=2ALCL +3HO; Aluminium oxide, chemical formula ALO. It is a compound with high hardness, melting point of 2054 and boiling point of 2980, ionic crystals that can be ionized at high temperatures, and are often used in the manufacture of refractory materials.

There are many homogeneous crystals, and there are more than 10 known at present. Appearance of the family stove, white amorphous powder; Insoluble in water, soluble in strong alkali and strong acid.

Aluminum with dilute nitric acidChemical reactionsThe equation is as follows:

al+4hno3=al（no3）3+no↑+2h2o

Aluminium withConcentrated nitric acidThe chemical reaction equation is as follows:

AL+6HNO3 (concentrated) = AL(NO3)3+3NO2 +3H2O (condition: heating).

Aluminium withCopper nitrateReactingChemical equationsAs follows:

2al+3cu（no3）2=2al（no3）3+3cu

Cu does not react with aluminum nitrate, the activity of Cu is not as good as aluminum, and AL can not be replaced if it is an acidic aluminum nitrate solution, and nitrate has strong oxidation under acidic conditions.

From the chemical properties, it can be seen that they themselves are not reacting, but the aluminum ions in aluminum nitrate undergo a hydrolysis reaction to produce hydrogen ions: Al (trivalent) + 3H2O = Al (OH) 3 + 3H+ In this way, the nitric acid oxidation condition is constituted in the solution, then copper and dilute nitric acid react to form copper nitrate and water and nitric oxide.

Hello! From the chemical properties, it can be seen that they themselves are not reacting, but the aluminum ions in aluminum nitrate undergo a hydrolysis reaction to produce hydrogen ions: Al (trivalent) + 3H2O = Al (OH) 3 + 3H+ In this way, the nitric acid oxidation condition is constituted in the solution, then copper and dilute nitric acid react to form copper nitrate and water and nitric oxide.

Al hydrolysis, Al+3H2O=Al(OH)3+3H (1)Cu reacts with NO3 under acidic conditions 3Cu+8H+2NO3=3Cu+2NO+4H2O (2) So 8(1)+3(2)=8AL+12H2O+9Cu+6NO3=8AL(OH)3+9Cu+6NO Note, the valency is not written.

Is it aluminum sulfate or aluminum nitrate, you can see again, there is only silver nitrate and aluminum sulfate on the handout.

It shouldn't react, copper is weaker than aluminum, and it won't be replaced, but aluminum ions will be hydrolyzed in water, I don't know if this service doesn't meet the original question.

The equation for the chemical reaction of aluminum and concentrated nitric acid is as follows:

AL+6HNO3 (concentrated) = AL(NO3)3+3NO2 +3H2O (condition: heating).

Chemical equation: Al2O3 + 6HCl ==2ALCL3 + 3H20; The positive ion equation is: Al2O3 + 6H+ =2Al3+ +3H20.

According to the query question bank test questions: the reaction equation of alumina and hydrochloric acid Answer: 1) Chemical equation:

Al2O3 + 6HCl ==2ALCl3 + 3H20 (2) Ion equation: Al2O3 + 6H+ =2Al3+ +3H20 Alumina is an amphoteric oxide, which can react with both acids and alkalis, both to produce salt and water!

Aluminium oxide is a type of repentant inorganic, chemical formula Al2O3, is a high hardness compound, melting point of 2054, boiling point of 2980, ionization at high temperature can be ionized vertical crystal, often used in the manufacture of refractory materials.
