Boric acid formula

I'm working on an experiment in school and I need to create 200mL of 2mol/L boric acid. According to a formula I found on wikipedia, boric acid can be created with a reaction with hydrochloric acid. $$\ce$$ So to calculate the amount of moles of boric acid needed, I multiplied the volume with the concentration to get 0.4mol. After using the molar ratios in the equation, the molar mass of borax decahydrate and the concentration of HCl, I calculated that I would need 38.14g of borax and 33.56mL of 5.96mol/L HCl in order for a complete reaction. After mixing these together, I ended up with about 40mL of a really thick solution, which is not the intended 200mL. What did I do wrong and how do I actually create boric acid of this volume and concentration? Am I missing steps in between? Assuming that boric acid is completely soluble in water, you did everything correctly so far, you simply missed the last step: dilution. First you calculated the amount of substance of boric acid you would need to produce a two molar solution. With that you basically assume, that you dissolve solid boric acid in water. You then calculated the amount of borax you need for complete reaction with hydrochloric acid. Since this is already hydrogen chloride dissolved in water, you bring some of the water you assumed before. But this is as your calculation says only about 40mL. Still assuming that it is completely soluble, you would have produced a solution that is about ten molar. You still need to dilu...

Oxides Boron oxide, B 2O 3, is made by the dehydration of boric acid, (6.7.1). It is a glassy solid with no regular structure, but can be crystallized with extreme difficulty. The structure consists of infinite chains of triangular BO 3 unit (Figure \(\PageIndex\): Structure of the metaborate anion, [B 3O 6] 3-. Boric acid Boric acid, B(OH) 3, usually obtained from the dissolution of borax, Na 2[B 4O 5(OH) 4], is a planar solid with intermolecular hydrogen bonding forming a near hexagonal layered structure, broadly similar to graphite (Figure \(\PageIndex\): The structures of the borate anions (a) B 5O 6(OH) 4 -, (b) B 3O 3(OH) 4 -, and (c) B 4O 5(OH) 4 2 -. Borax, the usual mineral form of boric acid, is the sodium salt, Na 2[B 4O 5(OH) 4], which upon dissolution in water re-equilibrates to B(OH) 3. Enough to make your hair curl In 1906, a German hairdresser, Charles Nessler who was living in London, decided to help his sister who was fed-up with having to put her straight hair in curlers. While looking for a solution, Nessler noticed that a clothesline contracted in a wavy shape when it was wet. Nessler wound his sister’s hair on cardboard tubes; then he covered the hair with borax paste. After wrapping the tubes with paper (to exclude air) he heated the entire mass for several hours. Removing the paper and tubes resulted in curly hair. After much trial and error (presumably at his sisters discomfort) Nessler perfected the method by 1911, and called the process a permane...

Formula and structure: The chemical formula of boric acid is H 3BO 3 (or B(OH) 3). Its molecular formula is BH 3O 3, and its molar mass is 61.83 g/mol. The chemical structure of boric acid is shown below: The central boron atom is connected to three hydroxyl (-OH) groups, which are capable of strong hydrogen bonding. Its solid crystalline structure consists of parallel layers of boric acid held together in place by hydrogen bonds. Occurrence: Boric acid occurs naturally in volcanic areas, and in certain minerals such as borax (as sassolite). It is also found in sea water, plants, and fruits in small amounts. Preparation: Boric acid is prepared by reacting minerals such as borax (Na 2B 4O 7·10H 2O), with strong acids like HCl: Na 2B 4O 7·10H 2O + 2 HCl → 4 H 3BO 3 + 2 NaCl + 5 H 2O It can also be prepared by the hydrolysis of boron trihalides (such as BBr 3) or diborane (B 2H 6): BBr 3 + 3 H 2O → B(OH) 3 + 3 HBr B 2H 6 + 6 H 2O → 2 B(OH) 3 + 6 H 2 Physical properties: Boric acid is a white crystalline solid with a density of 1.435 g/mL, melting point of 170.9 °C and boiling point of 300 °C. Chemical properties: Boric acid is a weak monobasic acid, and is considered a Lewis acid. It dissolves in boiling water and in anhydrous sulfuric acid. When heated to high temperatures (over 170 °C), it undergoes dehydration to form metaboric acid (HBO 2): H 3BO 3→ HBO 2 + H 2O Uses: Boric acid is non-toxic with antibacterial properties, and it is mainly used as an antiseptic agent, acne...

Boric acid, also known as boracic acid or orthoboric acid, is a naturally occurring compound containing the elements boron, oxygen, and hydrogen (H 3BO 3). Boric acid crystals are white, odorless, and nearly tasteless. It looks like fine table salt in the granular form or like baby powder in the powdered form. Borates, the general term associated with boron containing minerals such as borax and boric acid, most commonly originate in dried salt lakebeds of deserts or arid areas (such as Death Valley, CA, Turkey, and China) or other geographic regions that expose similar deposits (such as the Andes Mountains in South America). Boric acid is one of the most commonly produced borates and is widely used throughout the world in the pharmaceutical and cosmetic industries, as a nutritional supplement, flame retardant, in the manufacture of glass and fiberglass, and in the production of wood preservatives to control pests and fungus.
