Question

1) Из каких оксидов можно получить следующие кислоты: HNO3, H3AsO4, HClO4? Составьте уравнения реакций получения этих кислот и уравнения их диссонации. Как назвать эти кислоты?

Answer 1

НNO3 получают из N2O5
N2O5+H2O=2HNO3
HNO3<=>H+ + NO3-
азотная кислота

H3AsO4 получают из As2O5
As2O5+3H2O=2H3AsO4
H3AsO4<=>3H+ + AsO4(3-)
мышьяковая кислота

HClO4 получают из Cl2O7
Cl2O7+H2O=2HClO4
HClO4<=>H+ +ClO4-
хлорная кислота

Answer 2

Obtaining Nitric Acid (HNO3)

To obtain nitric acid (HNO3), one of the possible methods is through the oxidation of ammonia. The reaction can be represented as follows:

Equation for Obtaining Nitric Acid: ``` 4NH3 + 5O2 → 4NO + 6H2O 2NO + O2 → 2NO2 3NO2 + H2O → 2HNO3 + NO ```

Equation for Dissociation of Nitric Acid: ``` HNO3 → H+ + NO3- ```

Obtaining Arsenic Acid (H3AsO4)

Arsenic acid (H3AsO4) can be obtained by the oxidation of arsenic trioxide with nitric acid. The reaction can be represented as follows:

Equation for Obtaining Arsenic Acid: ``` As2O3 + 4HNO3 → 2H3AsO4 + 4NO2 + H2O ```

Equation for Dissociation of Arsenic Acid: ``` H3AsO4 → 3H+ + AsO4^3- ```

Obtaining Perchloric Acid (HClO4)

Perchloric acid (HClO4) can be obtained by the reaction of chlorine gas with water, followed by the addition of oxygen. The reaction can be represented as follows:

Equation for Obtaining Perchloric Acid: ``` Cl2 + H2O → HCl + HClO 2HClO → 2HCl + O2 ```

Equation for Dissociation of Perchloric Acid: ``` HClO4 → H+ + ClO4- ```

Naming of the Acids

The acids obtained are named as follows: - Nitric Acid (HNO3) - Arsenic Acid (H3AsO4) - Perchloric Acid (HClO4)

These equations and methods are based on chemical reactions and processes commonly used in the laboratory and industrial settings
