How do you memorize the mantra of what substances in chemistry are soluble in water?

...Potassium, sodium, ammonium salt, soluble in water, nitrate in water, insoluble barium sulfate, calcium and silver sulfate, slightly soluble chlorine, insoluble silver, mercury, carbonate, only potassium, sodium ammonium, dissolved alkali, potassium sodium, barium calcium Most acids can be soluble. This one is the best!

There are: solubility formula 1 potassium sodium ammonium brine dissolved in water, nitrate into the water without a trace, insoluble lead sulfate and barium, as well as silver chloride mercurous, as for phosphate carbonate, most of the water is insoluble, carbon magnesium (magnesium carbonate) calcium sulfur (calcium sulfate) and silver sulfur (silver sulfate), slightly dissolved in water soluble formula 2 potassium, sodium, ammonium salt, nitrate; chloride except silver and mercury; sulfate removes barium and lead; Carbonic acid, phosphate, only soluble potassium, sodium, ammonium. Illustrate, the above four ballads summarize the 8 types of dissolved and insoluble in water.

Solubility formula 3: Potassium, sodium, ammonium, nitrate are soluble, hydrochloride is insoluble silver, mercurous; Sulfate is insoluble barium and lead, carbon phosphate is mostly insoluble. Most acids are less soluble, only potassium, sodium, ammonium, barium, solubility, potassium, sodium, nitrate soluble, (potassium salt, sodium salt and nitrate are soluble in water.) Hydrochloric acid except silver (mercury), (hydrochloride is soluble except silver chloride and mercurous chloride.)

Speaking of sulfate, barium and lead are not allowed, (the insoluble in sulfate are barium sulfate and lead sulfate.) The rest of the salts, (carbonates, sulfites, phosphates, silicates, and sulfides) are soluble only potassium, sodium, and ammonium, (only the corresponding potassium salts, sodium salts, and ammonium salts are soluble) and finally alkalis, potassium, sodium, ammonium, and barium. (Potassium hydroxide, sodium hydroxide, barium hydroxide, and ammonia are soluble) There are also several microsolubles that can be remembered separately.

Solubility formula 5 potassium sodium ammonium salt nitrate is not difficult to dissolve completely mercurricular chloride silver chloride barium sulfate and lead sulfate to generate precipitation between hydrosulfates and alkalis carbonate phosphate nitrate soluble only potassium sodium ammonium solubility formula 6, 1 potassium, sodium, ammonium, pin dissolved 2 hydrochloride in addition to agcl 3 sulfate in addition to barium sulfate 4 carbonate more sinking 5 alkali soluble potassium sodium barium 3 6 acid soluble, silicic acid in addition solubility solubility formula 7 potassium sodium ammonium salt nitrate, all-soluble in the middle of water. Potassium hydroxide, sodium barium, calcium solubility. Chloride is insoluble in silver chloride.

There is also microsoluble calcium and silver. Carbonates are mostly precipitated, but are fully soluble in acids. （ps：

That is, the only thing that is insoluble in water in chloride is silver chloride) Sulfate insoluble barium sulfate, ) solubility formula 8, potassium sodium ammonium salt nitrate, it is not difficult to dissolve in water Except for silver in hydrochloride, barium precipitation in sulfate nitrate dissolves potassium sodium ammonium, potassium sodium barium calcium soluble alkali solubility formula 9, I take the cover alkali soluble NH4 K na ba ca I take carbonate soluble NH4 K na chloride silver insoluble barium sulfate insoluble acid in addition to silicic acid completely soluble In fact, they are all the same, you pick a catchy answer to add.

Potassium, sodium and ammonia salts are soluble, and there is no trace of aceate in water, acid and silicic acid are soluble, and alkali is insoluble in addition to potassium, sodium, barium, and ammonia. This is our junior high school mantra, I hope it will help you.

Remember the special, like insoluble, slightly soluble, just a few, what mantra, it's all floating clouds.

Recite a sentence 22 times, then you won't forget.

The mantra for the solubility of substances is that all nitrates are soluble in water. Hydrochloride insoluble silver and mercury, sulfate insoluble lead and barium, phosphate silicate carbonate sulfurite, only potassium sodium ammonium salt soluble in water, hydrosulfate is similar to the above phase, acid except silicic acid is all soluble in water, potassium sodium ammonium salt dissolves water quickly, sulfate removes barium, lead and calcium, chloride insoluble silver chloride.

Characteristics of the solubility of frectinSolubility is a kind of physical substance in the formation of a solution, it refers to a property of the solubility of a substance in a specific solvent, solubility refers to the chemical equilibrium of the solution can not hold more solutes, according to the solubility of the substance at 20 degrees of different size, the solubility of the substance is usually described by the concept of soluble, soluble, slightly soluble, insoluble, etc.

Solubility refers to the degree to which a substance can be dissolved, it refers to a property of the solubility of a substance in a specific solvent, the dissolved substance is called solute, and the liquid that dissolves other substances is generally called solvent in excess, and each part is usually the mass of each part of the solvent, and sometimes the maximum value of the solute that the solution can dissolve is the solubility of the solute in this solvent.

Salt that doesn't dissolve in water, right?

Potassium, sodium, ammonium salt, nitrate, can dissolve in the middle of water.

Silver and mercury in hydrochloride and barium and lead in sulfate.

Without them, they can be dissolved, and with them they will precipitate.

The solubility of those inorganic in chemistry should be clear for the most part. Let me talk about the solubility of organic matter, our teacher's induction. Most of the organic matter is insoluble in water, and the following are the organic matter that is insoluble in water.

1.Hydrocarbon. 2.Halogenated hydrocarbons.

3.Esters, oils and fats.

4.Cellulose.

5.Nitro compounds.

Alcohols, aldehydes, and acids with a number greater than or equal to 10.

Organic matter that is easily soluble in water.

of alcohols, aldehydes, acids.

2.Sodium salt. 3.The more hydroxyl groups, aldehyde groups, and carboxyl groups contain, the more soluble they are in water.

4.Organic matter is miscible with each other.

Potassium sodium ammonium nitrate salt soluble, bicarbonate and oxygen are mostly insoluble; Silver chloride in hydrochloride and barium insoluble in sulfate.

Potassium, sodium, ammonium saline is soluble, and nitrates have the same properties;

Sulfur "salts do not dissolve barium with lead,

Chlorine "salts are insoluble silver mercurous; ②

Weak alkali and weak acid salt, most of which are insoluble in water.

Note: "Sulfur" salt, refers to sulfate.

"Chlorine" salt, refers to hydrochloride.

Solubility of salts.

All sodium and potassium salts are dissolved, and the same is true for ammonium salts and nitrates.

Except for barium sulfate and lead, mercurous chloride and silver are insoluble, sulfite, phosphate, sodium, potassium, ammonium are insoluble, carbonate and silicate are all similar to the above.

Potassium sulfide, barium, sodium, magnesium soluble, calcium sulfide slightly soluble remainder insoluble.

Salt solubility song.

Potassium nitrate and sodium are soluble, carbon silicon and sulfur, hydrochloric acid are insoluble after mercury and sodium. Sulfuric acid to macrolimb barium lead, slightly soluble lead chloride, phosphate salts are mostly insoluble.

Calcium silver mercury sulfate.

Note: None of the metal salts in the solubility table after sodium are soluble in water.

Solubility of acid and alkali salts.

Potassium, sodium, ammonium salt, nitrate, can be soluble in water, hydrochloric acid in addition to silver and mercury, sulfuric acid is insoluble is barium lead.

Phosphoric acid carbonate is not soluble, the dissolver only has potassium sodium ammonium, the alkali has potassium sodium ammonium and barium, and magnesium salt is added to the sulfide starvation.

The rest are insoluble, slightly soluble in a few minds:

There is only one calcium in the alkali, mercury and calcium silver are sulfates, only lead is in chloride, and the attached magnesium is sulfurous acid;

There is calcium in the sulfide, and it is not difficult to memorize it.

The main alkali and salt solubility formula.

Potassium, sodium, ammonium, nitrate, solubility.

Potassium salt, sodium salt, ammonium salt, nitrate fully soluble).

Hydrochloric acid except silver, mercury (Hg+), agcl and hg2cl2 in hydrochloride insoluble) sulfuric acid insoluble barium, lead, sulfate in baso4 and pbso4 insoluble) dissolved alkali only potassium, sodium, barium, calcium, ammonium.

Ca(OH)2 is slightly soluble

Carbonic acid, phosphate, only soluble potassium, sodium, ammonium.

You can memorize this without a formula.

Generally, the substance soluble in water must be honored with the liquid clear code acid and base.

In the case of precipitation, weak bases such as copper hydroxide can be dissolved in acids.

There are only a few substances that are insoluble in water.

1.Weak. You should know that the hydroxides formed by the metals behind the kcabana are not soluble in water, but these can be soluble in acids.

2.There is also trouble in the weak acid, but it is not required in junior high school, it is h2sio33Salt looks at it this way.

1.Potassium, sodium, ammonium salt, and nitrate are all soluble in water.

2.Other salts that are insoluble in water are AGCL, BASO403A lot of carbonates are insoluble in water, you just have to write down the ones that are soluble in water, only Na2CO3, K2CO3

NH4) 2CO3, i.e. potassium sodium ammonium salt. There is also MgCO3 which is slightly soluble.

PS: There are very few slightly soluble substances, only MgCO3, CaSO4, Ca(OH)2, etc.

Potassium sodium ammonium nitrate dissolving.

There are five types of sosoda.

Barium, potassium, calcium, sodium, ammonia.

Insoluble chloride AGCL

Insoluble sulfate BaSO4

Carbonate dissolves only potassium and sodium ammonium.

The meaning of the formula: Substances containing potassium, sodium, nitrate, and ammonium are all soluble in water.

The alkalis soluble in water are: barium hydroxide, potassium hydroxide, calcium hydroxide, sodium hydroxide.

and ammonia, other bases are insoluble in water.

Only AgCl is insoluble in water, and the others are soluble in water;

Contains SO42

The compound is only BaSO4

Insoluble in water, everything else is soluble in water.

Contains CO32

The only substance that contains K+

Na+NH4+ is soluble in water, and everything else is insoluble in water.
