Borax Formula - Overview, Structure, Properties & Uses

What is borax powder?

Borax Meaning: Borax is a compound that contains a first substance called boron, which is combined with oxygen and soda. The Borax formula which is also known as the sodium borate formula, sodium tetraborate formula and or disodium tetraborate formula is described here in this article. Borax is a combination of soft, colourless Boron and can be dissolved in water. The main types of borax are anhydrous and decahydrate salt and sometimes as pentahydrate salt.

Borax Chemical Formula and Borax Chemical Name

The most common type of borax formula is Borax decahydrate which contains 4 atoms in Boron with 17 oxygen atoms, 2 sodium atoms, and 20 hydrogen atoms.

The chemical and molecular formula of Borax is:

Borax Natural Resources

The naturally occurring borax is purified by regeneration.

Borax can also be synthesized from boron chemicals.

Borax reaction

Borax is widely used in laundry and other cleaning products. It is also used to prepare boric acid by reacting with hydrochloric acid, HCl. This procedure was first used by Wilhelm Homberg.

The Borax powder reacts with hydrochloric acid to produce boric acid.

The reaction is as follows:

Na2B4O7 · 10H2O + 2 HCl → 4 B (OH) 3+ 2 NaCl + 5H2O

Borax Reaction - Each residual sugar in the polymer has two hydroxyl groups placed in the cis- form. This leads to an interesting and important reaction with the separated borate ions which is a feature of such polymers.

Borax Powder Uses:

Borax is known to act as a precursor to the essential chemicals of boron, the most important of which is boric acid (widely used as an insecticide).

It is not uncommon for borax to be used by photographic engineers as alkali.

Borax is also used as a flow of certain metallurgical processes.

This compound is known as the coordinating agent in the preparation of slime.

This field of biochemistry is known for its extensive and important use of borax in the production of buffer solutions.

In many cooking techniques, this combination is known to work as a messaging agent.

Borax is also used in neutron storage centers for safety, transport, and the use of radioactive material.

This compound is also known to act as an antifungal agent and, therefore, can be used to kill mold or prevent its growth.

It can also be noted that borax has the ability to act as a flame retardant.

Many cosmetic products, crustaceans, and detergents are known to contain borax.

The use of Borax formula in the removal of temporary and permanent water stress

Liquid borax solutions can be introduced into hard water for the purpose of softening water. Calcium (Ca2+) or magnesium (Mg2+) ions present in heavy water are replaced by sodium ions. Therefore, the hardness of the water is removed.

Chemical estimates of this reaction are given below.

Na2B4O7 (aq) + Mg2 + (aq) → 2Na + (aq) + MgB4O7 (s)

Na2B4O7 (aq) + Ca2 + (aq) → 2Na + (aq) + CaB4O7 (s)

Therefore, it can be understood that borax can be used in the removal of temporary and permanent water hardness. It does this by replacing the calcium or magnesium ions present in solid water with sodium ions.

Therapeutic Use of Borax

For the treatment of fungal infections of the feet, borax is widely used in the antifungal properties of the foot.

Borax is also a component of several available vitamin supplements for sale.

Thrush, the most common bacterial infection that occurs in horsehouses, can be treated with the help of borax.

Other Uses for Borax

Borax (with a mixed solution) can be used to treat wood and wood products infested with woodworm.

Metalworkers are known for their use of borax through a solid welding process in a condition known as forge welding.

Borax is also believed to act as a preservative in taxidermy. In addition, this combination can also act as a healing agent for snake skins.

To control the pH of swimming pools, it is common for borax to be added as a given buffering agent.

This mixture can also be used to prepare soil that lacks boron. It does that by acting like a little manure.

Borax Features

The molar weight of waterless borax is 201.22 grams per mole.

The given decahydrate form of borax has a molar weight of 381.38 grams per mole.

Under normal temperature and normal pressure conditions (STP), borax exists as a white solid.

The borax formula form without anhydrous weighs 2.4 grams per cubic centimeter. The amount of decahydrate is equal to 1.73 grams per cubic centimeter.

The melting and boiling points of the waterless form of borax correspond to 743 oC and 1575 oC respectively. The melting point of decahydrate is approximately equal to 75 oC. It can be noted that decahydrate begins to decompose at this temperature.
