  2. What is Borax? Borax is a natural mineral with a chemical formula Na2B4O7 • 10H2O. The IUPAC name for borax is sodium tetra borate decahydrate. Borax also is known as sodium borate, sodium tetra borate or disodium tetra borate. It is one of the most important boron compound.

  3. History of borax. • The name of this mineral comes from Arabic as Buraq/ Baurach. Boron (Borax) is named as “sodium tetra-borate” and “disodium tetra-borate” in Chemistry. • It is believed that the first source of Borax was found on Tibetan Lakes. Even though there is no solid evidence, it is believed that the Babylonians have been importing borax from the Far East over 4000 years ago for working on gold.

  4. History of Borax. • Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to Arabia. • Borax first came into common use in the late 19th century when Francis Marion Smith's Pacific Coast Borax Company began to market and popularize a large variety of applications under the famous 20 Mule Team Borax trademark, named for the method by which borax was originally hauled out of the California and Nevada deserts in large enough quantities to make it cheap and commonly available

  5. IUPAC name • Sodium tetraboratedecahydrate

  6. Properties • Molecular formula Na2B4O7·10H2O or Na2[B4O5(OH)4]·8H2O • Molar mass 381.38 (decahydrate) 201.22 (anhydrate) • Appearance white solid • Density 1.73 g/cm3 (solid) • Melting point 743 °C; 1,369 °F; 1,016 K (anhydrate[1]) • Boiling point 1,575 °C; 2,867 °F; 1,848 K

  7. Borax Uses • Borax has many uses on its own, plus it is an ingredient in other products. Here are some insect killer. • fungicide • herbicide • desiccant • laundry booster • household cleaner • ses of borax powder and pure borax in water:

  8. Borax Uses • Borax is an ingredient in several other products, such as: • buffer solutions • flame retardants • teeth bleaching products • glass, ceramics and pottery • enamel glazes • precursor for boric acid • for science projects such as green colored fire, slime, and borax crystals

  9. How does borax clean? • Borax has many chemical properties that contribute to its cleaning power. • Borax and other borates clean and bleach by converting some water molecules to hydrogen peroxide (H2O2). This reaction is more favorable in hotter water. • The pH of borax is about 9.5, so it produces a basic solution in water, thereby increasing the effectiveness of bleach and other cleaners.

  10. Risks Associated with Borax • Borax is natural, but that does not mean it is automatically safer for you or for 'the environment' than man-made chemicals. Although plants need boron, too much of it will kill them, so borax can be used as an herbicide. Borax may also be used as an insecticide to kill roaches, ants, and fleas. In fact, it is also toxic to people

  11. Some risks. • Signs of chronic toxic exposure include red and peeling skin, seizures, and kidney failure. The estimated lethal dose (ingested) for adults is 15-20 grams; less than 5 grams can kill a child or pet. For this reason, borax should not be used around food. More commonly, borax is associated with skin, eye, or respiratory irritation. It is also important to point out that exposure to borax may impair fertility or cause damage to an unborn child.
