Now this puzzle me, if only from the formula itself, does Borax dissolved in water and released 12 OH- ions (Four from OH, and 8 from H2O)? Now, of course that doesn't sound right, looking at the chemical structure of borax (see link:http://tiny.cc/yxeydz, figure 1), without ...

One mole of Borax [Na2B4O7], one mole of Sulfuric Acid [H2SO4] and twelve moles of Methanol [CH3OH] react to form four moles of Trimethyl Borate [B(OCH3)3], one mole of Sodium Sulfate [Na2SO4] and seven moles of Water [H2O] Reactants Bora...
Borax is generally described as Na2B4O7·10H2O. However, it is better formulated as Na2[B4O5(OH)4]·8H2O, since borax contains the [B4O5(OH)4]2− ion. In this structure, there are two four-coordinate boron atoms (two BO4 tetrahedra) and two three-coordinate boron atoms (two BO3...
Boron is not found free in nature, although boron compounds have been known for thousands of years. Boron occurs as borates in borax and colemanite and as orthoboric acid in certain volcanic spring waters. The primary source of boron is the mineral rasorite, also called kernite, which is fo...
