The true meaning of NaCl saturation

NaCl saturation means that there are no more Na ions and Cl ions in the solution?

Answer: The saturated solution of a substance only means that the substance can no longer be dissolved, and for other kinds of substances, it can still continue to be dissolved, saturation is actually a state in which the dissolution and precipitation rate are just in equilibrium, that is, the dissolution equilibrium, and for other kinds of substances, it can still continue to be dissolved.

If you add a compound containing Cl, can it still be absorbed? For example, if I pass HCl gas through the solution, will the gas be absorbed?

A: Yes.

Yes, saturation is in fact a state in which the rate of dissolution and precipitation is exactly in equilibrium.

In general, a saturated solution of a substance simply means that it can no longer be dissolved, and for other kinds of substances, it can still be dissolved.

It can be absorbed, as can be seen from the example of saturated salt water for the absorption of HCl gas in chlorine gas.

Naclo is sodium hypochlorite. Sodium hypochlorite is the "chlorine" bleach used in most common household washes. It is usually stored in a cool, ventilated warehouse.

Naclo is sodium hypochlorite. Sodium hypochlorite is the "chlorine" bleach used in most common household washes. Other similar bleaching agents are potassium hypochlorite, lithium hypochlorite or calcium hypochlorite, sodium hypobromide or sodium hypoiodate, chlorine-containing oxide solutions, chlorinated trisodium phosphate, sodium trichloroisocyanurate or potassium, etc., but are not usually used in household washing.

Bleach is a variant that destroys the color system or produces a co-color group.

1. It is used for the bleaching of pulp, textiles (such as cloth, towels, undershirts, etc.), chemical fibers and starch;

2. Soap industry used as a bleach agent for grease;

3. The chemical industry is used to produce hydrazine hydrate, monochloramine and dichloramine;

4. Chlorinating agent used in the manufacture of cobalt and nickel;

5. It is used as water purification agent, fungicide and disinfectant in water treatment;

6. The dye industry is used to manufacture vulcanized royal blue;

7. The organic industry is used to manufacture chloropicrin, calcium carbide hydration to acetylene detergent;

8. Agriculture and animal husbandry are used as disinfectants and deodorants for vegetables, fruits, feedlots and livestock houses;

9. Food-grade sodium hypochlorite is used for the disinfection of drinking water, fruits and vegetables, and the sterilization and disinfection of food manufacturing equipment and utensils, but it cannot be used in the food production process with sesame as raw materials.

Precautions for operation: Closed operation, full ventilation. Operators must be specially trained and strictly follow operating procedures.

It is recommended that the operator wear a direct gas mask (half mask), wear chemical safety glasses, wear anti-corrosion overalls, and wear rubber gloves. Prevent vapor leakage into the workplace air. Avoid contact with acids.

When handling, it is necessary to load and unload lightly to prevent damage to the packaging and containers. Equipped with emergency equipment for spill treatment. Empty containers may leave harmful substances behind.

Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30. It should be stored separately from acids, and should not be mixed. The storage area should be equipped with emergency response equipment for spills and suitable containment materials.

There is a precipitate-dissolved equilibrium in the saturated solution of NaCl.

Features: 1) Inverse: The precipitation and dissolution process is reversible;

2) etc.: v precipitate = v dissolve;

3) Fixed: The solute mass fraction in the solution remains unchanged;

4) Dynamic: Balance is dynamic;

5) Change: The balance is established under certain hail conditions, when the sail conditions change, the balance will be broken, and a new balance will be established.

At the same temperature, the saturated sodium chloride solution cannot continue to dissolve the sodium chloride, while the unsaturated sodium chloride solution can continue to dissolve the sodium chloride, which is the difference between the two.

At a certain temperature, a solution that can no longer dissolve a certain solute in a certain amount of solvent, that is, a solution that has reached the solubility of the solute is a "saturated solution". A solution that continues to dissolve a solute at the same temperature, i.e., a solution that has not yet reached the solubility of the solute, is an "unsaturated solution". If the solute is a gas, the pressure of the gas is also indicated.

A concentrated solution is not necessarily a saturated solution, and a dilute solution is not necessarily an unsaturated solution, but with the same kind of solute, the saturated solution must have a greater concentration than the unsaturated solution.
