How to remember the solubility table of chemical salts and alkaline acids in junior high school??? T

Acid-base salt solubility formula:

Potassium, sodium, ammonium nitrate, soluble alkali, there are five kinds of barium, potassium, calcium, sodium ammonia.

Insoluble chloride, agcl, insoluble sulfate, baso4, carbonate, only soluble potassium, sodium ammonium.

The meaning of the formula: The substances containing potassium, sodium, nitrate, and ammonium are soluble in waterThe alkalis soluble in water are: barium hydroxide, potassium hydroxide, calcium hydroxide, sodium hydroxide and ammonia, and other alkalis are insoluble in water.

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

Only BaSO4 is insoluble in water, and the others are soluble in water.

The substances containing CO32 are only soluble in water with K+ Na+ NH4+, and the others are insoluble in water.

Memorize the mantra. Potassium, sodium, ammonium nitrate are soluble (compounds containing potassium, sodium, nitric acid, ammonium, all soluble) hydrochloric acid insoluble silver mercury (silver chloride, mercurous chloride precipitate).

Lead barium sulfate is insoluble (lead sulfate, barium sulfate precipitate).

Calcium, silver, mercury is slightly soluble (calcium sulfate, silver, mercurous microsoluble).

There are five soluble bases.

Potassium, sodium, barium, ammonium, calcium slightly soluble (potassium hydroxide, sodium, barium, ammonium soluble, calcium hydroxide slightly soluble), hydrosulfur thionite soluble three (potassium, sodium, ammonium).

Carbon-silicon phosphoric acid is the same as above.

The acid is all soluble, the alkali is only ammonia, sodium hydroxide, potassium hydroxide, barium hydroxide and calcium hydroxide are soluble, salt: potassium, sodium, ammonium salt, nitrate are all soluble, hydrochloride is only silver chloride, sulfate is only barium sulfate insoluble, carbonate is mostly insoluble.

If you feel that rote memorization is easy to forget, then do more questions so that the memory is fresh.

Slip of the tongue: potassium hydroxide, barium calcium-soluble, chloride only silver insoluble, barium sulfate not calcium, silver micro, potassium, sodium, ammonium nitrate are all soluble.

I give you a formula. You just have to take this back. You can achieve long-term memory. But you can't rely on this alone. To understand. Otherwise, when people ask you, you will count with your fingers. How incompetent. I made it up myself. Give points.

Formula] potassium, sodium, ammonium, nitrate dissolved.

There is no salt that does not dissolve in water.

Chloride. To remember.

Only silver is insoluble. (Silver chloride).

Sulfate. Much soluble.

Only the barium rests in the water. (barium sulfate).

Carbonates are simple.

Ammonium potassium sodium soluble in water. (Potassium carbonate.) Sodium carbonate. Ammonium carbonate. Carbon, magnesium, alkali, calcium, sulfur, silver, calcium. (Magnesium carbonate.) Calcium hydroxide. Silver sulphate. Calcium sulphate. It doesn't dissolve very much. (slightly soluble).

Alkali silver, aluminium carbonate and iron. (Silver hydroxide.) Aluminium carbonate. Iron carbonate. A horizontal must be able to write. ("Refers to the absence of a substance or its decomposition upon contact with water") nitric acid and carbonic acid.

There is also ammonium hydroxide in volatilization. (Ammonium hydroxide).

Others not mentioned above.

Throw it in water and soak it only. (i.e. insoluble).

Potassium, sodium, ammonia, nitrate, dissolved in water is not difficult; chloride except silver mercurous, sulfate except barium and lead; Carbonate phosphate, only dissolved in potassium, sodium and ammonia.

Potassium sodium, calcium barium tetraalkali soluble, potassium sodium ammonium salt is soluble, nitrate into the water without a trace, chloride salt insoluble barium chloride, sulfate insoluble barium sulfate, carbonate only dissolves potassium sodium ammonium.

Probably potassium, sodium, ammonium salts are soluble, barium sulfate, silver chloride, insoluble. Then there is hydrogen and oxygen, most of the carbonates are not tolerated, and it would be good to remember a few more that do not exist.

Potassium, sodium, ammonium nitrate are soluble (compounds containing potassium, sodium, nitric acid, ammonium, all soluble) Insoluble silver mercury hydrochloride (silver chloride, mercurous chloride precipitate) Lead barium sulfate insoluble (lead sulfate, barium sulfate precipitate) Calcium, silver, mercury is slightly soluble (calcium sulfate, silver, mercury slightly soluble) Soluble alkali has five positions Potassium sodium barium ammonium calcium slightly soluble (potassium hydroxide, sodium, barium, ammonium soluble, calcium hydroxide slightly soluble) Hydrosulfur thionite soluble three (potassium sodium ammonium) Carbon-silicon phosphoric acid is the same as above.

potassium, sodium, ammonium salt, nitrate, can be soluble in water;

Hydrochloride is insoluble in silver chloride, sulfate is insoluble in barium sulfate, carbonate is soluble in potassium sodium ammonium, alkali is soluble in potassium sodium ammonium and barium;

There are also four microlyses:

Calcium hydroxide, calcium sulfate, magnesium carbonate, silver sulfate.

The mantra taught by our teachers.

Make up your own formula:

Insoluble in water, "calcium, iron, zinc, manganese and copper, divalent and carbon are insoluble."

Barium sulfate, barium carbonate, put in the water and turn into taste.

Silver chloride is difficult, silver carbon is difficult, only nitric acid plays with it.

Magnesium, aluminum, zinc, iron, copper, manganese, hold up to hydrogen and oxygen.

The substance does not exist or decomposes in water".

Three-iron aluminum, when it encounters carbon, it is either a lie or a vain.

Silver ions, so noble, absolutely not with hydrogen and oxygen.

Slightly soluble in water "Magnesium and carbon, silver and sulfur, put together is slightly soluble.

Calcium hydroxide sulfate is slightly soluble.

volatile".

Hydrogen ions, good volatile, sulfuric acid drag not surprised.

Potassium and sodium ammonium dissolve the world, and the ammonium root should be volatilized afterwards.

Description: "soluble" means that the substance is soluble in water, "not" means insoluble in water, "micro" means slightly soluble in water, "volatile" means volatile, "—means that the substance does not exist or decomposes when it encounters water.

The condition of the metathesis reaction is that there is water, gas, or precipitation formation, right, if there is precipitation formation, this judgment is used.

Then there is the question of whether the ions in the solution can coexist, if the horizontal line is not tolerated or slightly soluble, there will be precipitation formation, and it cannot coexist.

The chemical formula is a group of atoms or ions that make up a molecule, and when paired horizontally and vertically, they form a substance. (The box says whether it is tolerated or not).

Silicic acid is insoluble, potassium salts, ammonium salts, and salts containing nitrate are all soluble. You don't have to memorize them one by one.

Silver chloride and barium sulfate are insoluble in acid and water, and with the addition of another one, silver sulfate is also insoluble in acid and water like them.

The last sentence can be combined.

Potassium, sodium, ammonium salt, nitrate, all dissolved is not difficult.

To memorize this sentence, you only need to remember that only potassium carbonate, sodium carbonate, and ammonium carbonate are soluble in carbonates, and everything else is insoluble.
