Is it possible for a molecular crystal to contain ionic bond pairs

Wrong. As long as a substance contains ionic bonds, it must be an ionic crystal, and it is also an ionic compound.

Answer]: ANAF is an ionic compound, so the manuscript is mainly based on silver ion bonds.

1 At least some ionic crystals, such as NaCl, have only ionic bonds and no intermolecular forces. Some of the atomic clusters may have hydrogen bonds between them.

1. After forming barium sulfite, it dissolves to form barium bisulfite, which has no gas and no precipitation.

2. In an acidic environment, nitrate causes an oxidizing environment, and sulfite is oxidized to sulfate, so there is a precipitate and a reduction product NOX

3. Negative divalent sulfur and sulfite generate sulfur elemental precipitate, no gas.

4HCl is more acidic than sulfurous acid and bisulfite, and it is not reactant.

5. Oxidation. Depending on the situation, calcium sulfate is slightly soluble and will precipitate without gas.

6 with 2, oxidation, there is gas but iron sulfate does not precipitate, if SO2 is enough, it will be oxidized by ferric iron, and ferrous sulfate is still soluble.

7. Hydrogen peroxide oxidizes and becomes water and sulfuric acid, and there is no gas and no precipitation.

8 is the same as 5, but sodium sulfate is soluble in water, so there is no gas and no precipitation.

9. Phenol is not as acidic as bisulfite, does not react, 4, no, and may also be ionic crystals.

Right:

There is a precipitation, BaSO3 white precipitate Oxidize SO2 to form sulfate, generate barium white precipitate thiordanachloric acid Neutralize the reaction, generate S elemental Reaction Does not react Oxidize SO2 to produce calcium sulfate, slightly soluble in water, you will see a white precipitate Nitrate is reduced to nitrogen dioxide - gas Hydrogen peroxide is reduced to water, sulfur dioxide is oxidized to sulfuric acid Sodium hypochlorite is reduced to water, sulfur dioxide is oxidized to sulfuric acid Reaction to form phenol. 2. Only chemical bonds may be atomic crystals, ionic crystals or metal crystals, and only molecular crystals have intermolecular forces.

Neither precipitated nor gaseous are barium hydroxide, barium chloride, hydrogen peroxide, sodium hypochlorite, sodium phenol.

Causes: Barium hydroxide, which dissolves after precipitation of barium chloride, does not react.

Hydrogen peroxide, which produces sodium hypochlorite sulfate, sodium chloride and sodium phenol sulfate, produces phenol and sodium bisulfite. 2. Is it true that a compound crystal that only contains chemical bonds and no molecular force must be atomic crystals? How many are there that have neither precipitation nor gas after sufficient amount of SO2 is introduced into the following solutions?

Barium hydroxide, barium nitrate, sodium sulfide, barium chloride, calcium hypochlorite, ferric nitrate, hydrogen peroxide, sodium hypochlorite.

Sodium phenol Please indicate which ones are correct? And describe in detail why these substances can produce such a phenomenon or cannot produce this phenomenon.

The atoms in the atomic crystal are connected to each other by covalent bonds, forming a spatial network structure. Such as carbon atoms in diamond, silicon atoms and oxygen atoms in silica. That is, there is only one force in the atomic crystal, covalent bonds.

The basic particles in a molecular crystal are molecules. Such as solid carbon dioxide. In crystals, there are chemical bonds (covalent bonds in the inner part of the carbon dioxide molecule) inside the elementary particles (carbon dioxide molecules), and there are weak intermolecular forces (van der Waals forces) between the elementary particles (between carbon dioxide molecules), which determine the hardness, melting point, and boiling point of the molecular crystal.

That's why.

Ionic crystals are composed of anions and cations, and the interaction between ions is a strong ionic bond. The representative substances of ionic crystals are mainly strong bases and most salts. The structural characteristics of ionic crystals are:

The particles on the crystal lattice are cations and anions; The inter-particle force on the crystal lattice is the ionic bond, which is relatively strong; There are only anions and cations in the crystal, and the ion crystal may contain molecules, such as CuSO4·5H2O. Nature characteristics, generally mainly in these aspects:

It has a higher melting point and boiling point, because to melt the crystal, it is necessary to break the ionic bonds, and the ionic bonds are stronger, so they need to be heated to a higher temperature. Hard and brittle. Most ionic crystals are soluble in water.

Ionic crystals have ions when they are in a solid state, but they cannot move freely and cannot conduct electricity, and when they are dissolved in water or melted, the ions can move freely and can conduct electricity.

Be. The concepts of ionic compounds, ionic crystals, and substances containing ionic bonds are different, and their relationships are as follows

Ionic crystals must be ionic compounds.

Ionic compounds are not necessarily ionic crystals, and the state of matter needs to be observed. For example, NaCl exists in the gaseous form of a molecule, which can never be called an ionic crystal.

Ionic crystals necessarily contain ionic bonds, but they can also contain covalent bonds at the same time. For example, in NH4Cl crystals, NH4+ and Cl are ionic bonds, but NH4+ is covalent between N and H (including coordination bonds).

That's right, what contains a covalent bond is not necessarily a covalent compound, but as long as it contains an ionic bond, it must be an ionic compound, an ionic crystal.

It must be, as the name suggests, that's what it means.

But there can be covalent bonds in ionic crystals.
