Is salt mixed with water and boiled to get salt?

Will you get salt after mixing salt and water together for boiling, because salt and water are mixed together and after being boiled dry, you will not get salt anymore due to volatilization.

The dissolution of salt in water itself is a chemical reaction. Strong acids and alkali salts are dissolved in water, the original anionic bonds are broken, and the anion and cation are combined with water molecules to form new anionic bonds. If there is a weak acid and a strong alkali salt or a strong acid and a weak alkali salt, not only the above reaction will occur, but also the hydrolysis reaction will occur, so that the solution is weakly acidic and weak.

Some of these can be immediately noticed, for example, in order to increase the rate at which salt dissolves, we can speed it up by stirring it quickly, but this can also cause water or brine to splash out of the cup. This splash may or may not be visible to the naked eye.

One would think that since human manipulation is prone to mistakes, if it is not stirred, it is quietly left there and waiting for the salt to slowly dissolve? That's not good. Over time, the water will slowly evaporate into the air.

In an open container, if you leave it for three to five days, it may even disappear. In addition, we must also take into account that there may also be substances in the air that dissolve into water or salt water, factors that can affect the final weight. So, to really know how many exact results a pound of water has for a pound of salt, you need to put them in an airtight container of known weight, and the container itself does not react with the air very quickly.

The salt and water that are mixed together should be separated: the salt is obtained by evaporation and recrystallization, distilled, the water is steamed out, and the rest is the salt at home, and the water can be evaporated, but the salt will remain. However, this is not necessarily the case with industrial salts, some industrial salts will undergo chemical reactions when heated and become something else.

Salt is mixed with water and boiled to dry, because it is melted and then sublimated.

Yes, because that's the process of extracting salt, which is extracted from some water.

After the salt and water are mixed together and boiled dry, the salt will not be obtained due to volatilization.

Yes, because the salt itself is dried out of seawater, it crystallizes again when the salt water is boiled dry.

No, the salt and water will melt away after mixing, and then it will be steamed and dried.

After mixing and boiling dry, you will definitely get salt, which is equivalent to crystallization.

Of course this thing does, and they'll re-smoke it when they're done.

You should get it, after all, it's a very simple chemical process.

I think this one will definitely do, but the salt content is relatively small.

I think this is possible, after all, if the temperature is not high, it will cause salt precipitation.

The salt in the brine is soluble in the water, when the brine is boiled, as the water boils, resulting in a decrease in the water, the dissolved salt decreases, and when the salt exceeds the solubility in the water, it will precipitate.

Solubility: solubility, the quality of the solute dissolved by a solid substance when it reaches saturation in 100g of solvent at a certain temperature, which is called the solubility of the substance in this solvent. The solubility of a substance is a physical property.

Factors influencing solubility:

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.

The most fundamental reason is that salt is solid at normal temperatures, (unlike iodine, which is easily sublimated), and the water is evaporated when the brine is heated, and the evaporated water is in two states: water vapor (liquid) and gaseous. The rest is salt.

But it is not pure salt, because salt is easily deliquent in the air, which is what we usually call salt moisture.

The water turned into water vapor and evaporated.

The salt in the water is getting thicker and thicker.

When a critical value is reached, the salt is precipitated.

It is assumed that the volume of brine extracted per unit is v cubic meters.

Then the extracted brine mass m(ys) = brine v

kg we think of the extracted brine as adding salt to v cubic meters of water (if the salt is completely dissolved in water, the change in water volume can be ignored).

v cubic meter water mass m(s) = water v

kgSo the mass of salt m(y)=m(ys)-m(s)=(brine - water) vkg The mass of salt contained in brine per cubic meter t = (brine - water) v v=) = brine - water.

You can say salt.

It is useless unless you have to take into account the volume of salt dissolved in water.

then the system of equations is solved.

Salt v salt + water v water = brine v

v salt + v water = v

Because we assume that v is known.

A system of binary linear equations.

Both sides of the two types ride the same water.

Phase subtraction yields v salt = ( brine - water) v ( salt - water) so t = v salt * salt v = salt ( brine - water) v ( salt - water).

2NaCl + H2O = (electrolytic) = 2NaOH + H2 + Cl2

Energizing is one of the strongest redox means, Cl- loses electrons, H+ obtains electronic physical and chemical properties, which can be distinguished from the following three aspects:

Some properties need to be analysed on a case-by-case basis. Such as:

Some substances are insoluble in water but soluble in acid, is the "dissolution" here a physical or chemical property?

Generally speaking, soluble in water is a physical property and soluble in acid is a chemical property.

Most metals are insoluble in water, which means that under normal conditions, the quality of the solid is difficult to change when the metal is placed in water. Many metals are soluble in acids, meaning that they can react with acids to produce hydrogen and soluble salts. Similarly, limestone and marble are not soluble in water, but they can be soluble in hydrochloric acid.

Because they can react with hydrochloric acid to form a water-soluble calcium chloride and release carbon dioxide at the same time.

Physical change, chemical change: whether new matter is formed.

Chemical properties: the properties of substances that are manifested in chemical changes such as flammability, oxidation, physical properties: properties that can be directly realized without chemical changes such as color, odor, and stateExample: Determine the properties of utilization.
