Ethene has a very reactive double bond, and if mixed with bromine in organic solvent, it will undergo an addition reaction, where the two bromine atoms will adjoin onto the ethane molecule (because the double bond has broken, it now becomes an alkane (ethane) - more specifically it will form 1,2 - dibromoethane.
C2H4 (g) + Br2 (tetrachloromethane) -------------------> CH2Br-CH2Br (aq)
However, when bromine is dissolved in water instead, HOBr(aq) will be formed, subsequently the reaction becomes:
C2H4 (g) + HOBr (aq) -------------------> HO-CH2-CH2Br (aq)
Still, the brownish - reddish colour of the bromine water will decolourise.
This is a useful way of distinguishing between alkanes and alkenes of similar molecular weights.
