It dissolves slightly in water, forming a bleaching solution. Chloride of Bromine .-- This as an accelerating agent is by many considered superior {75} to the other Bromide combinations.
It can be readily prepared by passing a current of chlorine through a vessel containing bromine.
A mixture of two parts muriatic acid and one of black oxide of manganese, should be put into a flask having a bent tube to conduct the chlorine vapor into the bromine in another vessel.
This last vessel should also be supplied with a bent tube for conducting the combined vapors with a third vessel or receiver.
On the application of the heat from a spirit lamp to the bottom of the flask, a current of chlorine gas will be disengaged, and pass into the bromine, when it readily combines, and gives off a vapor, which, when condensed in the third vessel, forms a volatile yellowish-red liquid.
