Is it true that compounds that contain only metal ions and acid radicals belong to the salt category

It should be. Logically, it is not wrong to judge only the compounds that meet the conditions of "only metal ions and acid groups" to be salt. Replacing the metal element with H is an acid, and replacing the acid root with (OH) is an alkali, which is really nothing to dispute.

It should be noted, however, that the reverse of this sentence does not make sense, because acid or base salts can be produced in the case of incomplete reaction between acid and base.

For example, I learned at the beginning of chemistry, basic copper carbonate, Cu2(OH)2CO3 It belongs to acid salts, but it is not a compound that only contains metal ions and acid radicals.

This sentence is true, compounds with metal ions and acid radicals must belong to the salt group.

But you can't say the other way around, because.

Some salts do not have metal ions in them, such as ammonium salts.

NH4Cl is also found in some salts.

Except for acid and metal ions or ammonium.

There may be. Hydroxide.

As. Cu2(OH)2CO3, belongs to.

Basic salts.

Wrong. A compound composed of metal ions (or ammonium ions NH4+) and acid ions.

Salts containing hydrogen ions are called acid salts, such as: ammonium bicarbonate (NH4HCO3); Sodium bisulfate (NaHSO4); Potassium phosphate monobasic (KH2PO4).

Salts containing hydroxide ions are called basic salts, such as: basic copper carbonate (Cu2 OH 2CO3) salts that do not contain hydroxide ions and hydrogen ions are called normal salts, such as: sodium chloride (NaCl); Sodium carbonate (Na2CO3). In addition, there are double salts (such as alum) and so on.

I think that's right. Because compounds are divided into three categories: acid-base salts, since they are not acid-bases, they are salts.

Hello, this sentence is wrong, and the statement to strive for should be: compounds containing metal ions and acid radicals belong to the salt group.

Wrong. Salt can be made up of many components.

There are several types of salt. Positive salt: metal ion + acid (NaCl) acid salt: metal ion + H + acid group.

For example: NaHCO3 (sodium bicarbonate).

Basic salts: metal ions + OH + acid groups.

For example: (Cu)2(OH)2CO3

Basic copper tanate).

It is composed of metal ions (including ammonium ions) and acid ions.

Classification of salt. Positive salts: composed of metal ions (including ammonium ions) and non-metal ions alone

Composed of metal ions (including ammonium ions), hydrogen ions, acid ions, and non-metal ions Basic salts: composed of metal ions (including ammonium ions), hydroxide ions, acid ions, and non-metal ions Double salts: composed of different metal ions (including ammonium ions) and acid ions Basic salts explained in detail The anions formed during ionization include hydroxide ions in addition to acid ions, and the cations are salts of metal ions (or NH4+).

1. Salt is a compound composed of metal ions (including ammonium ions) and acid ions.

2. Table salt, also known as table salt, is one of the most important substances for human survival, and it is also the most commonly used seasoning in cooking. The main chemical component of salt is sodium chloride.

Chemical formula NaCl) is 99% in table salt, and potassium chloride is added to the table salt produced in some areas.

to reduce the amount of sodium chloride to reduce high blood pressure.

At the same time, salt in most parts of the world is prevented by the addition of terrestrial iodine, which is called iodized salt.

Salt is generally combined, because in the process of producing salt, H ions and oxygen ions combine to form water, hydrogen ions are gone, and what is left is acid radicals, and if there are no hydroxide ions, metal ions or ammonium ions are left, so salt can only be composed of "metal ions (including ammonium ions)" and "acid ions".

In chemistry, salt refers to a class of metal ions or ammonium ions (NH4+) compounds combined with acid ions or non-metal ions, such as calcium sulfate, copper chloride, sodium acetate, generally speaking, salt is the product of metathesis reactions, such as sulfuric acid and sodium hydroxide to produce sodium sulfate and water, and there are other reactions that can generate salts, such as displacement reactions.

Salt is divided into single salt and combined salt, single salt is divided into normal salt, acid salt, basic salt, and combined salt is divided into double salt and complex salt. Among them, the acid salt contains hydrogen ions in addition to metal ions and acid ions, and the basic salt contains hydroxide ions in addition to metal ions and acid ions. When complex salts are dissolved in water, complex salt complexes of complex ions that are different from the original salts can be generated.

In general, insoluble salts are solid under standard conditions, but there are exceptions, such as molten salts and ionic liquids. Soluble salts and molten salts are electrically conductive and can therefore be used as electrolytes. The cytoplasm, blood, urine and mineral water of the cells, contain many different salts.

Strong alkali weak salt is a salt that reacts with a strong base and a weak acid, which is alkaline when dissolved in water, such as sodium carbonate. The strong acid and weak alkali salt are the salts that react with strong acids and weak bases, and are acidic when dissolved in water, such as ferric chloride.

Salts: Compounds in which metal ions or ammonium ions are combined with acid ions.

This is the definition of salt, in fact, the process of generating salt (such as the neutralization reaction) requires acid and base, the hydrogen ion of the acid is gone, leaving the acid ion, and the hydroxide ion of the alkali is gone, leaving the metal ion or ammonium ion, and the combination of the two is salt.

The definition of salt is like this, for example: AGCL, silver chloride, which is composed of metal silver ions and acid chloride ions.

In the aqueous solution of hydrochloric acid and para-lead brine, the same ions that must be contained are: () Qiqi.

a.Metal is a good omen.

b.Hydrogen ions.

c.Acid ions (correct answer).

d.Hydroxide ions.

Salt and alkali are two different chemical concepts.

In chemistry, salt is a chemical compound that is made up of cations and anions, which are held together by ionic bonds. Normally, salts are composed of metal ions and non-metallic acid ions (or non-metal anions), such as sodium chloride (NaCl), copper sulfate (CuSO4), potassium nitrate (KNO3), etc. When metal ions combine with non-metallic acid ions to form salts, it is usually accompanied by acid-base neutralization reactions.

Whereas, a base is a chemical compound that usually refers to a substance that is capable of producing hydroxide ions (OH-) in an aqueous solution. Bases are usually metal hydroxides (e.g., sodium hydroxide Naoh, calcium hydroxide Ca(OH)2, etc.) or other compounds that produce hydroxide ions. Alkali reacts with acid to produce salt and water, a process known as acid-base neutralization.

Although alkalis and salts can be composed of metal ions and acid ions in some cases, they have different properties and uses for finch parsley. Alkali is usually an alkaline solution that neutralizes acidic substances; Whereas, salts can be acidic, neutral, or alkaline, and their properties depend on the combination of ions in them. Therefore, although NaOH is also composed of metal ions and acid ions, it is called a base rather than a salt because it produces hydroxide ions in an aqueous solution and has alkaline properties.

It's hydroxide, not acid.
