Mass of the formula properties 87. 81 freezing point, 90 the specific temperature for boiling 130 c vapour pressure 5 mmhg The density of vapor is equal to that of air, Rated at 1 3 ability to dissolve in water miscible density 1. 28g/cm3 for 40% and 1. 38 g/cm3 for 50% hbf4 solution at 20 c. Composition hbf4 40, 48. 00% free boric acid 2. 60% so4,, 0. 05% ci, 0. 03% fe 0. 03% heavy metals 0. 02% uses as catalyst for to clean, Esterifying cellulose, Preparing acetals metal surfaces in alzak, Before welding process for the electrochemical brightening of aluminum, Reagent for sodium in presence of magnesium & as solute, Potassium ions in electrolytes for plating alloys including chromium, Iron, Nickel, Copper, Silver, Zinc, Cadmium, Indium, Tin, & lead has high throwing power, Using as a ph modifier in baths for electroplating metals from fluoborate solutions. Fluoboric acid is employed for clean lead and its alloys prior to electroplating. It functions as for cleaning in addition to the inscription of metal surfaces owing to the high solubility of oxide and silicate films that might possibly be on the metal textures. It functions as stripping solution for removal of solder metal plating from baser metals. Small additions of fluoboric acid have been proposed for particularly for, Phosphating baths because the, Light metals protective coatings are thereby improved. Catalyst for alkylation s and polymerizations. Reagent for sodium in the inclusion of magnesium and potassium ions, For making stabilized diazo salts diazonium & tetrazonium fluoborates, 0. 1, 0. 5% solution retards fermentation.
