General information

Soda is the common name for all sodium s alts of carbonic acid. The chemical name of baking soda is sodium bicarbonate, sodium bicarbonate, baking soda, sodium bicarbonate (not to be confused with sodium carbonate - soda ash with the formula Na2CO3). The formula of drinking soda is NaHCO3. It is a powder of tiny white crystals with a s alty taste.

Natural soda is extracted from the mineral trona, as well as from the water of some lakes. However, soda lakes, as well as the mineral from which it is obtained, are few. Nowadays, most of the sodium bicarbonate is produced in factories. The artificial production of baking soda began in 1861.

Some chemical properties of soda

Despite the alkaline properties of the soda solution, for example, the neutralization of acids, chemically it is a s alt (acidics alt of sodium and carbonic acid). It is non-explosive, non-flammable under normal conditions, non-toxic. In acid solutions, soda decomposes into new acid s alts, carbon dioxide and water.

Does baking soda dissolve in water

As already mentioned, soda does not completely dissolve in acids, but turns into other substances. Does baking soda dissolve in water? The answer is yes, it dissolves well with the formation of other substances. In general, soda interacts better with hot water; it is slightly soluble in cold water. An aqueous solution of sodium bicarbonate has a slightly alkaline reaction. The characteristic hissing sound when soda dissolves is due to the release of carbon dioxide. The formula for the reaction of soda with water: NaHCO3 + H2O ↔ H2CO 3 (H2O + CO2) + NaOH. That is, when interacting with water, sodium bicarbonate decomposes into sodium hydroxide, which gives alkalinity to water, and carbonic acid, which, in turn, immediately decomposes into water and carbon dioxide.

The following are the solubility of sodium bicarbonate in water of different temperatures as a percentage (conventionally taken 1 gram of soda per 100 grams of water):

  • 6, 9 - 0°C;
  • 8, 2 - 10°C;
  • 9, 6 - 20°C;
  • 10, 4 - 25°C;
  • 11, 1 - 30°C;
  • 12, 7 - 40°C;
  • 16, 4 - 60°C;
  • 20, 2 - 80°C;
  • 24, 3 - 100°C.

Experiments with soda

At home, you can conduct a series of educational experiments with soda, demonstratingits properties. They will be of interest to both children and adults who love chemistry. You will need baking soda and acid (citric acid solution - 1-2 teaspoons per glass of water or 9% table vinegar).

  • Fill the bottle one third full with acid. Pour soda into a balloon, this can be done using a funnel. Put a ball on the neck of the bottle and start pouring soda into acid from it. The balloon will inflate with carbon dioxide from the bottle, formed as a result of the interaction of soda and acid.
  • Pour hot water into a glass container, pour more soda into it (for example, 15 tablespoons per glass) and stir until it finishes dissolving. Hang any small thing on a thread, fasten the thread on the outside, and immerse the object in the prepared solution. After about a day, the object will begin to be covered with soda crystals.
  • Take a pack of soda (or a little more) and shaving foam, mix them thoroughly. It should turn out not very sticky, but holding the shape of the mass. From this "artificial snow" you can make a snowman or any other New Year's decorations. When dried, it becomes crumbly, so if the properties of the mass need to be preserved longer, it is stored in the refrigerator.

The use of soda in everyday life

Of course, the main use of baking soda in the household is in cooking. Soda slaked with vinegar is used for baking - the dough is lush and soft. It can also be used to make homemade lemonade.

But there are other ways to use it, assodium bicarbonate has disinfectant properties and can eliminate unpleasant odors.

  • To clean and rid the refrigerator of bacteria, you can wash it from the inside with a warm solution of soda (a tablespoon per liter of warm water).
  • To disinfect plumbing, soda is applied to its surface. Then wipe them with a damp cloth or sponge and rinse with water.
  • There is a recipe for a paste with soda that cleans objects and surfaces from grease and stubborn dirt, as well as limescale. It is necessary to take 50 grams of baby soap (in bars), 550 milliliters of water, one and a half tablespoons of mustard powder and the same amount of soda. Rub the soap on a coarse grater and pour a little hot water into it. Stir, heating and gradually pouring in the remaining water until the soap dissolves. Pour soda in there. When the solution has cooled slightly, add mustard powder and beat the mixture.
  • To clean the walls from mold and fungus, you need to wash the affected surfaces with a concentrated solution of soda. Leave for a while, then rinse off with clean water. After the wall is dried and repainted.
  • To clean aluminum dishes, you need to add a teaspoon of soda to a liter of water and pour the dishes with this solution. Rinse after cleaning with warm water.
  • Contaminated areas of enamelware are wiped with dry soda powder using a sponge. It must be remembered that soda can leave small scratches on the enamel.
  • The degreasing effect of soda is used when washing greasy dishes with its aqueous solution. It is also able to eliminate tea plaque.

Soda is not used for cleaning wooden products, because the wood becomes reddish under its action.

Using baking soda for healing

The healing properties of baking soda are based on its inherent disinfection and acid neutralization.

Despite the usefulness of baking soda, it should be used with caution. Constant use of it inside leads to disruption of the gastrointestinal tract. Sodium bicarbonate neutralizes acids, therefore, reduces the acidity of gastric juice, resulting in problems with the digestion and absorption of food, and all the ensuing consequences. Some use soda for weight loss, but in this case it will be associated with poor he alth. And the introduction of a soda solution in the form of injections is all the more dangerous for humans and is completely unacceptable.

Recipes for home medicine

  • For sore throats, rinse with a solution of soda (a teaspoon per 250 grams of warm water). Inflammation of the gums, oral mucosa and toothache can also be relieved with this remedy.
  • Furuncles are treated with lotions with a concentrated soda solution, and corns are treated with baths of soda and hot water.
  • If a gruel of soda and water is applied to the place bitten by insects, the itching will decrease. The water should be cool, as the question: "Does baking soda dissolve in water?" the answer has already been given that it dissolves well in hot and warm water, and the slurry in this case will not work.
  • Forto get rid of heartburn, stir soda in warm water at the rate of 1 teaspoon per glass. They drink in one gulp. It is not necessary to abuse this, and if there are other antacids, it is better to take them. As an extremely rare, but occurring side effect, they describe a stomach rupture that occurred as a result of a sharp release of gases after taking soda (as mentioned above, carbon dioxide is released as a result of the interaction of soda with water and acids). Therefore, there may be a burp after taking a soda solution.

Beauty recipes

Also, sodium bicarbonate is used for cosmetic purposes.

  • For facial peeling and cleansing of skin pores, a small amount of soda is added to the usual portion of the cleanser, which is applied to the skin in a circular motion without rubbing. The agent is immediately washed off with warm water. As a result, dead skin cells are exfoliated.
  • To make a body scrub, you need to mix two tablespoons of baking soda with a moisturizer (milk, lotion). On wet skin, apply the mixture to the body with a washcloth. This product softens the skin and soothes irritation from shaving.
  • Soda solution can eliminate puffiness and circles under the eyes. Cotton pads moistened with it are placed on the eyelids and kept for about 15 minutes.
  • A mask is used for acne and pimples: mix a tablespoon of flour, half a teaspoon of soda and a little water so that a slurry is obtained. The resulting mixture is applied to the face for 10-20 minutes, then washed off with warm water.
  • Hair will become soft andshiny if their shampoo or conditioner is added to the bottle with a tablespoon of soda.

Use of baking soda in industry

In addition to everyday home use, soda is used in the chemical industry, where it is used to produce paints, polystyrene, reagents, household chemicals, fire extinguishers. In light industry, it is involved in the manufacture of rubber soles, artificial leather, as well as the processing of natural leather, in the finishing of silk and cotton fabrics. In medicine and pharmaceuticals, soda is used to reduce the acidity of gastric juice and neutralize acid burns on the skin.
