Solubility table how to understand dissolved insoluble insoluble 25

Take the inserted solubility table diagram to your question, the substances in the table are all water as solvents, and the solubility of the substance is between 1g and 10g or even more, and when it is greater than 10g, it is soluble; Micro - solubility between 1 g; Insoluble means that the solubility is less than and can almost be regarded as insoluble, (but there are almost no substances that actually dissolve a very small amount and are absolutely insoluble in water). At the same time, the solubility table should be understood under certain conditions, especially for aqueous solutions, especially temperature, the solubility has a greater impact, the higher the temperature, the greater the solubility, for gases, temperature and pressure have a great impact on solubility, the higher the temperature, the smaller the solubility of the gas, the pressure increases, and the solubility also increases. The solubility of the same substance varies greatly if it is in different solvents.

Soluble: The substance is soluble in water.

Difficult: insoluble in water (the solubility is less than that, and it can almost be regarded as insoluble, but it actually dissolves a very small amount, and there are almost no substances that are absolutely insoluble in water).

Micro: slightly soluble in water.

Volatile: volatile or easy to decompose.

Soluble as solubility greater than.

Slightly soluble to solubility.

Insoluble is less soluble than solubility.

Insoluble to almost negligible solubility.

The meaning of the mantra is:

Potassium salt, sodium salt, ammonia salt, nitrate can be soluble in water

Barium sulfate in sulfate is insoluble, and everything else is soluble

Chloride salts are soluble except for silver chloride

Carbonate only potassium carbonate, sodium carbonate, ammonia carbonate dissolved and others are insoluble, potassium hydroxide, sodium hydroxide, calcium hydroxide, barium hydroxide soluble (only in the junior high school range) solubility table is a combination of horizontal and vertical view, if you want to check the solubility of calcium carbonate, first find the carbonate in the horizontal header, and then find calcium ions in the vertical header, you can find calcium carbonate, the table says insoluble, that is, calcium carbonate is insoluble.

As for the function, it is to judge whether a substance is a precipitate, which can be used to judge whether the metathesis reaction can occur.

The knowledge about dissolution in junior high school is still very simple, high school and college will be further learned, and junior high school mainly stays at the memory level.

Hand forgetting.

Potassium salts, sodium salts, ammonia salts, and nitrates are all soluble in water, such as potassium chloride, ammonium sulfate, calcium nitrate, as long as this is the case.

Barium sulfate Silver chloride is intolerable Other sulfate chloride salts are soluble.

Carbonate only potassium carbonate, sodium carbonate, ammonia carbonate dissolved in the others are insoluble, potassium hydroxide, sodium hydroxide, calcium hydroxide, hydroxide, ., potassium hydroxide, potassium hydroxide, sodium hydrBarium hydroxide is dissolved, if you can't remember, you might as well take a look at the precipitate dissolution at the back of the chemistry book**, and then correspond to this mantra memory, I believe it will be of great use to you.

If you have any questions, please feel free to discuss them.

Salts of potassium ions, sodium ions, ammonium ions, and nitrate ions can all be soluble in water. Among sulfates, only barium sulfate is insoluble in water. in chlorine salts.

Only silver chloride is insoluble in water. Potassium carbonate, sodium carbonate, ammonium carbonate, soluble in water, potassium hydroxide, sodium hydroxide, calcium hydroxide, and barium hydroxide soluble in water (these are the things that are learned, in fact, this is not the case. These are common questions, and you will be able to do a few questions. ）

I've got a mantra that I've been using all the time, and I'm going to teach you a little bit like this.

Potassium, sodium, ammonia, and nitric acid are all dissolved.

Chloride is insoluble in silver chloride.

Sulfate is insoluble with barium sulfate.

Carbonate dissolves only potassium and sodium ammonium.

This is mainly used in the third year of junior high school to write reaction phenomena or precipitation gas symbols, and in high school, it is especially useful to write ion equations.

Ammonia, potassium, sodium, barium, calcium (I take the quilt cover) and hydroxide ions are combined with water-soluble substances.

The chemical solubility table also has this effect, just like the ordinary **.

In the junior high school range, potassium, sodium, ammonia salts and nitrates are soluble to whom, barium salts are soluble except for Baso4, and chloride salts are soluble except for AGCL.

Carbonate ions and potassium sodium ammonia ions are composed together and dissolved in water, while hydroxide ions only dissolve potassium, sodium, calcium and barium. Actually, this is not true.

Potassium, sodium, ammonium salts are soluble.

Nitric acid (salt) is nowhere to be found in water.

Sulfate (salt) is insoluble lead and barium.

Hydrochloric acid (salt) is insoluble in silver and mercury.

Solubility refers to the ability of a substance to dissolve in a solvent.

Solubility is determined by the solubility of a substance at 20 hours.

Solid) Insoluble (insoluble) Slightly soluble Soluble Soluble (20) 1g 10g >10g

Solubility is a measure of the size of a substance's solubility capacity;

Solubility, the mass dissolved by a solid substance when it reaches saturation in 100g of solvent at a certain temperature, is called the solubility of the substance in this solvent.

Solubility; The question of how much to dissolve.

Solubility; Problems with the nature of dissolution.

There is both a connection and a difference between the solubility of the two concepts of a substance and the solubility of a substance. The solubility of a substance, i.e., the magnitude of the dissolving capacity of a substance. This ability depends both on the nature of the solute and on its relationship with the solvent.

No matter how complex the cause or the factors affecting the solubility of a substance may be, it can simply be understood that it is a property of the substance itself. For example, table salt dissolves easily in water, but it is difficult to dissolve in gasoline. Grease is easily soluble in gasoline, but difficult to dissolve in water, etc. This property of salt and oil is an inherent property of itself, which can be summarized by the concept of solubility.

However, solubility is different, it is a "ruler" to measure the solubility of a substance according to the standards prescribed by people. Under the same specified conditions, different solutes can be dissolved in the same solvent in different quantities, which objectively reflect the difference in their solubility. Therefore, the concept of solubility not only contains the meaning of the solubility of substances, but also further reflects the specific quantity under specified conditions, which is the concretization and quantification of solubility, and is a concept formed after making provisions for the quantitative study of the solubility of various substances.

Soluble, soluble, slightly soluble, and insoluble are terms commonly used to describe the degree to which a substance dissolves in solution, and they do not have a well-defined cut-off value. The exact degree of solubility can vary depending on the context and experimental conditions. However, the following general descriptions can generally be used:

Soluble: refers to the fact that a substance can be fully dissolved in a given solvent to form a transparent and homogeneous solution. Most or all of the substance is dissolved in molecular or ionic form.

Soluble: Refers to the fact that a substance is soluble in a given solvent, but may be less soluble. The dissolved solution may not be completely transparent, or there may be a small amount of precipitated or suspended solids.

Slightly soluble: Refers to the low degree to which a substance is soluble in a given solvent. The dissolved solution is usually cloudy or has a pronounced precipitate, but a portion of the substance can still be observed in a dissolved state.

Insoluble: Refers to the fact that the substance is almost insoluble in a given solvent. The dissolved solution is usually cloudy or precipitate, with only a very small amount of material in a dissolved state.

It is important to note that the use of these terms is relative and depends on the properties of the solvent and solute used. The same substance may exhibit different degrees of solubility in different solvents. Therefore, in specific experiments and applications, it is also necessary to refer to the solubility data of the substance, the concentration of the solution, and other factors to more accurately describe the degree of solubility.
