Solubility is a physical property of a substance when it forms a solution. It refers to a property of the solubility of a substance in a particular solvent.

Solubility refers to the maximum amount of solute that a solution that reaches (chemical) equilibrium cannot hold more solutes, and refers to the maximum amount of dissolution of a substance in a particular solvent. Under special conditions, more solute is dissolved in the solution than normal, and it becomes a supersaturated solution.

A solution that reaches (chemical) equilibrium cannot hold more solutes (of course, other solutes can still be dissolved), which we call saturated solutions. If the solvent is not specified, it usually means that the solvent is water, e.g. "solubility of sodium chloride" and "solubility of sodium chloride in water" can be considered to mean the same thing. Solubility is not a constant value.

Salts soluble potassium, sodium, ammonium, nitrate into water without a trace, chloride insoluble silver chloride, sulfate insoluble barium sulfate, carbonate only soluble potassium, sodium, ammonium, alkali soluble barium and potassium, sodium, ammonium.

Most acids are soluble, and silicic acid is slightly soluble. Alkali potassium sodium barium ammonium soluble, calcium is slightly soluble and insoluble. Lead barium sulfate is immersed in water, slightly soluble calcium, silver and mercury.

The salts are dissolved with potassium, sodium ammonium, plus soluble nitrate. Carbonic acid can dissolve potassium and sodium ammonium, and the rest is submerged in the middle. Hydrochloric acid precipitates silver mercurous, as well as slightly soluble lead chloride.

(Potassium hydroxide, sodium hydroxide, barium hydroxide and ammonia are soluble).

There are also several microlyses that can be remembered separately.

Explanation Potassium salts, sodium salts, ammonium salts, nitrates are all soluble in water.

In addition to the above four, hydroxide and barium ions are also soluble in water when combined.

Sulfuric acid ** is insoluble in water when combined with barium ions, calcium ions, and silver ions, and everything else is soluble.

Carbonic acid** is soluble in water when combined with hydrogen ions, potassium ions, sodium ions and ammonium ions, and everything else is insoluble.

Chloride ions are insoluble in water only when combined with silver ions.

Carbonate only dissolves ammonium potassium sodium;

All nitric acids are soluble;

Hydrochloric acid is insoluble only in silver;

Sulfuric acid is insoluble only with barium.

Explanation Ammonium hydroxide, potassium hydroxide, sodium hydroxide, and barium hydroxide are all soluble in water, and the rest with hydroxide are insoluble in water.

Ammonium carbonate, potassium carbonate, and sodium carbonate are all soluble in water, and the rest with carbonate are insoluble in water.

All nitrates are soluble in water.

Only silver chloride is insoluble in water, and the rest are soluble in water. (Because chloride ions are present in hydrochloric acid, all chloride ions here are called hydrochloric acid.)

The solubility formula is: 1. Nitrates are all soluble in water, hydrochlorides are insoluble in silver and mercury, sulfates are insoluble in lead and barium, phosphoric acid, silicic acid, carbonic acid, sulfurous acid, only potassium sodium ammonium salt is soluble in water, hydrosulfate is similar to the above phase, and acid except silicic acid is all soluble in water. 2. Potassium, sodium, ammonium salt, nitrate; chloride except silver and mercury; sulfate removes barium and lead; Carbonic acid, phosphate, only soluble potassium, sodium, ammonium.

Solubility formula.

Common solubility formulas are as follows:

Sulfuric acid is only barium-insoluble, potassium carbonate, sodium ammonium salt, soluble.

The solubility formula table is as follows. The solubility mantra commonly used in chemistry is:

1. Potassium, sodium, ammonium, nitrate are soluble, hydrochloric acid is insoluble silver mercurous; Sulfuric acid is insoluble, barium and lead, and carbon phosphate are mostly insoluble; Most of the acids are soluble and less soluble, and only regret that there are potassium, sodium, ammonium, barium and calcium. Nitrate soluble potassium, sodium, ammonium, nitrate into water without a trace, chloride insoluble silver chloride, sulfate insoluble barium sulfate, carbonate only soluble potassium, sodium, ammonium, alkali soluble barium and potassium, sodium, ammonium. Most acids are soluble, and silicic acid is slightly soluble.

2. Alkali potassium, sodium, barium, ammonium soluble, calcium is slightly soluble and insoluble. Songyuan lead barium sulfate is immersed in water, slightly dissolved calcium, silver and mercury. The salts are dissolved with potassium, sodium ammonium, plus soluble nitrate. Carbonic acid can dissolve potassium and sodium ammonium, and the rest is submerged in the middle. Hydrochloric acid precipitates silver mercurous, as well as slightly soluble lead chloride.

Whether a substance is dissolved or not, and the size of its solubility depends on the nature of the substance (referring to solvents and solutes) on the one hand; On the other hand, it is also related to external conditions such as temperature, pressure, solvent type, etc. Under the same conditions, some substances are easily soluble and others are difficult to dissolve, i.e., different substances have different solubility in the same solvent. The ability of one substance to dissolve in another is usually referred to as solubility.

For example, sugars are easily soluble in water, while fats and fats are insoluble in water because they are different in their solubility over water. Solubility is a quantitative representation of solubility.
