FUCHSIN Magenta FULLERS EARTH Bleaching Earth FUMARIC ACID. AR Pure and Technical Grades are. Mixtures of borax and sulfuric acid are fed to a fusion furnace where molten boric oxide and sodium sulfate separate into layers at temperatures above 750 C.

The decanted boric oxide product typically contains 96-97 boric oxide. Kirk-Othmer Encyclopedia of Chemical Technology. 3rd ed Volumes 1-26.

John Wiley and Sons 1978-1984 p. Hazardous Substances Data. Boron trioxide is produced by treating borax with sulfuric acid in a fusion furnace.

At temperatures above 750 C the molten boron oxide layer separates out from sodium sulfate. It is then decanted cooled and obtained in 9697 purity. Another method is heating boric acid above 300 C.

Boric acid will initially decompose into steam H 2 O g and metaboric acid HBO 2 at around 170. Sodium hypochlorite commonly known in a dilute solution as bleach is a chemical compound with the formula NaOCl or NaClO comprising a sodium cation Na and a hypochlorite anion OCl or ClO It may also be viewed as the sodium salt of hypochlorous acidThe anhydrous compound is unstable and may decompose explosively. It can be crystallized as a pentahydrate NaOCl 5 H.

In a nitrogen oxide process sulfur dioxide is oxidized to sulfuric acid in an aqueous phase with nitrogen oxides serving as oxygen carriers.

Processes of this type include the lead chamber processes eg Mills - Packard and Gaillard and the tower processes eg Curtius Petersen Kachkaroff Matignon Salsasserra and Moritz. These processes formerly constituted the basis for sulfuric. Fusion of boric acid with sodium oxide forms a borate salt Na2B4O7.

Without writing complete equations find the mass in grams of B5H9 required to form 151 g of the borate salt by this reaction sequence. 2 NOg 5 H2 g - 2 NH3 g 2 H2Og A reaction mixture initially contains 5 moles of NO and 10 moles of H2. Without doing any calculations.
