Soda ash: 33 ways to use it at home, in the garden and in the garden

Sodium carbonate or soda ash is a common substance in many areas. Once upon a time, housewives could not do without it when washing dishes, and schoolchildren could not do without it when removing ink stains from the surface of the tables at which they studied. Today, sodium carbonate is in demand in the chemical industry and in the manufacture of food products; it is used in the production of glass and glass products, added to medicines and products for the care of problem skin, and used for oil production.

In appearance, the substance is a powder of small, barely visible grayish-white crystals - many may have observed it during school experiments. In addition to being a white powder, the reagent may also take the form of colorless crystals.

The substance is highly soluble in water and polyhydric alcohols.

There are two main varieties of sodium carbonate: industrial and food grade. The second is known under the symbol E500. Sodium carbonate is an indispensable aid when it comes to preparing baked goods and desserts.

However, if you delve deeper into the characteristics of the compound, you will find out that a whole group of substances is hidden under the name sodium carbonate:

• sodium carbonate, food additive E500 (i);
• sodium bicarbonate, food additive E500 (ii);
• a mixture of salts of the two above compounds, food additive E500 (iii).

Soda ash should not be confused with baking soda! Soda ash is sodium carbonate, baking soda is sodium bicarbonate.

History of discovery

Humanity became acquainted with laundry soda a long time ago - 2,000 BC. The ancient Egyptians extracted it from lake waters. Soda was used to melt glass and replaced a detergent.

The word “soda” comes from the phrase “solyanka”. This term denoted a plant that ancient people burned to obtain ash. Then it was heated to high temperatures, i.e. calcified. The substance obtained as a result of such actions was soda ash. Soda was mined in this way until the beginning of the 19th century.

The idea of ​​producing laundry soda artificially belongs to the French pharmacist N. Leblanc. He proposed to extract this substance by calcining a mixture of sodium sulfate, coal and crushed chalk. From this composition, sodium carbonate was leached with water, then the solution was evaporated, and pure soda ash was isolated. The released calcium sulfate was considered a production waste.

Subsequently, new methods for extracting laundry soda were developed, which produced much less waste.

In nature, large quantities of sodium carbonate are found in the form of underground ground brines, as well as brine in salt lakes.

Large deposits of this compound are located in Canada, the USA, Mexico, Kenya, and South Africa. There are soda lakes in Western Siberia and Transbaikalia.

Production

For centuries, soda has been extracted naturally from the Salsola soda plant, certain seaweeds, and as minerals. Only at the end of the 18th century, the French scientist N. Leblanc discovered the first artificial (chemical) method for producing soda ash. This method was complex and expensive, leaving many by-products.

In the 19th century, the Belgian chemist E. Solvay developed an economical method for producing sodium carbonate. This technology is still basic today. This method is called ammonia. Later, in the 30s of the 20th century, another method for producing soda was developed. The Chinese chemist Hou modified Saullier's method.

Advantages of the ammonia method:

• efficiency and low cost (cheap raw materials, low-cost process);
• easy extraction of raw materials, their wide distribution in nature;
• simplicity of the manufacturing method (the technical procedure is unchanged, the process temperature is no more than 100 degrees Celsius);
• high quality.

Today's market is served by more than 70 sodium carbonate production facilities. More than half of them are located in Europe (Figure 3). The key producing countries are China, the USA and the EU countries.

On the Russian market, production is represented by such enterprises as:

— Bereznikovsky soda plant (Perm region),

- (r. Bashkiria).

Difference from other soda

Laundry soda should be distinguished from baking soda and caustic soda

Baking soda, soda ash and caustic soda are representatives of sodium compounds. But these compounds differ from each other in chemical formula.

Baking soda is a safe product and can be used in everyday life and cooking. It can cause harm to health only if a person ingests a large amount of it.

Soda ash has a high pH value of 11. This compound is a strong alkali and can cause burns and allergies. Can only be used at home. Soda ash has good cleaning properties.

Caustic soda is an alkali that is good at removing stains, but can corrode organic matter. The cleansing effect of caustic soda is more pronounced in comparison with food and laundry soda. Caustic soda is a toxic substance.

Pest Control

Soda ash is also used in everyday life to control garden pests. To do this, prepare a simple solution. A bucket of clean water requires no more than 6 teaspoons of soda ash. The finished composition can be used to treat grape vines. This product protects plants from gray rot. It is worth noting that this solution is suitable for treating fruit plants. The product does not cause any harm, but allows you to protect plants from caterpillars and other pests.

In addition, the solution can be used to process cucumbers, zucchini, melons and cabbage. However, you should not get carried away with soda ash. Excessive amounts harm the soil. Which, in turn, can greatly affect the future harvest.

Benefits and harms of sodium carbonate

Soda ash is a beneficial compound and here's why:

• has good disinfectant and cleaning properties;
• helps remove blockages from sewer pipes;
• approved for use for washing clothes, machine or hand;
• effectively removes scale from the internal surfaces of washing machines and dishes;
• can be used to soften hard water;
• Helps fertilize the soil and destroy garden pests.

Despite many advantages, baking soda also has disadvantages:

• at high concentrations in the air it can cause an explosion;
• may cause burns and skin irritation as it creates an aggressive alkaline environment.

Peculiarities

The chemical formula of soda ash is Na2CO3. It is also called sodium carbonate or sodium carbonate. It is white in color and comes in the form of granules or powder.

The substance has no characteristic odor and dissolves in water. Crystals easily absorb moisture and odors. In this case, sodium carbonate carbonates can release acidic salts.

Soda ash is produced by processing minerals and also through the ammonia-soda process.

Applications of sodium carbonate

Sodium carbonate is widely used in a wide variety of human activities:

• in gardening;
• at home;
• in handicrafts, etc.

This substance is also used to disinfect premises where animals are kept, in the textile, automotive and chemical fields.

• Brand B is used as a component for creating synthetic detergent compositions in the oil, paint and varnish, and paper industries.

Precautionary measures

Soda ash is toxic and causes severe poisoning if it enters the body. When using, you must follow a few simple rules:

• Before use, be sure to wear rubber gloves;
• store in a dry place, separate from food and medicines;
• Keep out of the reach of children;
• in case of contact with eyes or mouth, rinse immediately with plenty of water;
• be sure to comply with the required proportions.

Storing soda ash

Sodium carbonate is a friable powder without lumps. In special packaging it can be stored for up to 5 years. Once the container is opened, baking soda can be stored for up to 25 days.

Sodium carbonate actively absorbs moisture from the air. If the package in which it is contained is open, the compound loses its properties and gradually cakes.

After opening the package, it is better to store the soda in a glass container, tightly closing it with a plastic lid. The bank must definitely sign it.

Security measures

Since sodium carbonate is not as safe as baking soda, it must be used with certain precautions:

1. wear rubberized household gloves to protect the epidermis of the hands;
2. keep such a substance away from medications and food;
3. choose a storage place where this soda cannot be reached by a small child;
4. if the substance gets into the eyes, nose or mouth, then they must be rinsed very well and be sure to use running water for this;
5. You must use soda ash carefully, and be sure to follow the recommended proportions in order to avoid possible troubles.

When choosing a place to store such a substance, you should remember that it absorbs moisture and carbon dioxide. In this regard, long-term storage of sodium carbonate in open packaging may cause it to cake and reduce its volume.
