Make bromide

Make bromide Tube. Duration : 8.47 Mins.

As hydrogen bromide. potassium bromide (240g.) is dissolved in water (400ml.) in a glass and the glass is cooled in the ice or in a bath with cold water. concentrated sulfuric acid (180ml.), then is slowly added. We must ensure that the temperature does not exceed 75 degrees can have a bit more 'bromine are formed. The solution is cooled to room temperature and potassium bisulfate, which has separated is cooled, is removed by filtration through a hardened filter paper in a BuchnerFunnel. The filtrate is distilled from a liter flask, and the collected fraction 124-127 bp, which contains trace amounts of sulfates. Pure constant boiling hydrobromic acid is obtained from the distillation of a small barium bromide speech. The yield is about 285g. or 85%. the theory.
