The most concentrated HBr + Aq has a sp. gr. of 1 -78, and contains 82-02 % H Br. (Champion and Pellat, C. R. 70. 620.) This, or a weak acid on heating leaves a residue, which dis- tils unchanged at 125-125-5 under 758 mm. pressure, a nd contains 48-17 % HBr (Top.soe) ; at 126' under 758 mm. prcssuro, and contains 46-83 % HBr (Bineau) ; and has sp. gr. = 1-486 at 20 (Bineau) ; sp. gr. = 1 -48 at 20° (Champion and Pellat) ; sp. gr. =1-49 at 20 (Topsoii). According to Roscoe (A. 116. 214) an acid of constant composition, obtained by boiling a stronger or a weaker acid, if distilled^under 752-762 mm. pressure, contains 47-38-47*86 % HBr, and boils at 126° at 760 mm. pressure ; but the composition is dependent on the pressure, as, for example, under 1952 mm. pressure, the residue boils at 153°, and contains 46-3 % HBr. (Roscoe.) By conducting dry air through HBr-l-Aq an acid is obtained containing 51-65 % HBr if at 16°, and 49-35 % HBr if at 100° (Roscoe.) 1 vol. HoO dissolves 600±vols. HBr at 10°. (Berthelot, C.
