Why do we need boric acid in everyday life and industry?

Wikipedia states that the application of boric acid is very diverse.

In agriculture, it is used as a fertilizer (especially valuable is boron dressing for grapes), as well as for spraying tomatoes and a number of other crops.

In laboratories, the substance is used to prepare buffer solutions, in nuclear reactors - as dissolved neutron absorber in the coolant, in photography - as part of solutions and gels for developing and fixing a photographic image, in the food industry in some countries - as a preservative E284.

In the foundry industry, boric acid acts as a binder in the acid lining of furnaces, and also protects against jet oxidation during casting of magnesium-based alloys. Jewelers add it to the solder flux.

In everyday life, boric acid is used to kill cockroaches and ants. In addition, it is used for fishing: mixed with bread and thrown to fish for feeding. From the words of fishermen, the fish from such a treat “gets drunk” and floats to the surface.

Overdose

  • erythematous rash,
  • shock and development coma.

Within 5-7 weeks there is a chance of death.

Symptoms of chronic intoxication are:

Symptomatic treatment is indicated to the patient, hemo-andperitoneal dialysis, blood transfusion.

Fatal for an adult is a dose of 5 to 20 g. Such a large variation is due to the fact that the substance is excreted from the body by the kidneys. Consequently, the better this pair body works, the easier it will be for a person to suffer poisoning.

Since in children the renal function is relatively underdeveloped (and the lower the child’s age, the more pronounced this underdevelopment is), boric acid is most dangerous for young children and, in particular, for newborn babies.

What is boric acid?

Boric or orthoboric acid in accordance with the value of its dissociation constant is a weak acid. Acidic properties are determined not by cleavage of the H + -proton, but by addition of a hydroxide anion.

Boric acid is easily replaced by most other acids from solutions of its salts (borates). Salts are produced, as a rule, from polyboric acids, the acidic properties of which are much more pronounced (for example, tetraboric acid H2B4O7).

The formula of the substance is H₃BO. The Latin name is Acidum boricum.

The use of boric acid in gardening

Boric acid is widely used in the garden and garden as a micronutrient for various crops.

The use of boron preparations in horticulture and horticulture for pre-sowing seed treatment, the main application to the soil before planting seed, spraying and foliar feeding of plants during the growing season helps to improve the nutrition of the ovaries and increases the flow of sugars to the organs of sexual reproduction of plants.

Dicotyledonous plants, which include almost all fruit and vegetable crops, are absorbed 10 times more boron than cereals, which belong to the class of monocotyledonous plants. The greatest amount of trace element accumulates in the pulp of apples.

The most sensitive to boron deficiency are grapes, potatoes, tomatoes, fodder roots, pears, apples, sugar beets. When it is inadequate, the growing point is suppressed, the interstices are shortened, fragility of leaf petioles increases, the tubers grow small and some of them crack, the stem grows black in tomatoes and the fruits become covered with brown spots of dead tissue, the fruit necrosis develops on apples and pears.

The effectiveness of boron as a fertilizer for plants is highest on sod-podzolic and peat soils.

Boric acid spraying of tomatoes, strawberries, cucumbers, cabbage helps to increase the ovary and stimulates the formation of new growth points, increases the concentration of vitamins in fruits and increases the resistance of crops to adverse weather conditions.

Feed boric acid tomatoes and strawberries (as well as a number of other fruit and vegetable crops) reduces the likelihood of diseases associated with a lack of boron (including a hollow stem and red / brown rot in cauliflower, heart rot, scab and cork root crops, root scabs).

How to spray grapes and other fruit plants? The greatest increase in yield can be achieved with double spraying: during the setting of the buds and during flowering.

For processing using a solution of boric acid (5-10 g) and zinc sulfate (5 g). Even a one-time carrying out of such a procedure before flowering makes it possible to increase the productivity of plants by 20-36%. The introduction of boric acid in a mixture with superphosphate during the softening of the berries contributes to the increase of sugar in the berries and the improvement of their taste.

Use during pregnancy

Boric acid is contraindicated in pregnancy. Even a single intake of a non-toxic dose into the mother can cause pathological changes in the fetus.

Reviews of boric acid - this is primarily reviews of boric acid from acne and reviews on the use of means from cockroaches and other small insects.

Many women and girls believe that boric acid gives an even better result than salicylic. With its regular use, the skin becomes healthy after 5-30 days of use (depending on its initial state).
