Question

Why is Bromine water brown?

Answer 1

Bromine:

1. Bromine is chemically represented by the symbol $\mathrm{Br}$.
2. It has an atomic number of 35.

Bromine water:

1. Bromine water is a powerful oxidizer and is somewhat acidic.
2. Bromine water is brown in color due to the presence of Bromide ions.

${\mathrm{Br}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\rightleftharpoons \mathrm{HBrO}\left(\mathrm{aq}\right)+{\mathrm{H}}_3{\mathrm{O}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Br}}^{-}\left(\mathrm{aq}\right)$
