A bromine diagnostic test is used to classify a colorless liquid as saturated or unsaturated. The test involves adding bromine water (Br2(aq)) to the liquid, mixing and observing the final color of the bromine water.
The evidence statement that would positively identify an unsaturated liquid compound is: |
|
|
|
The mixture when shaken becomes yellow and solidifies. |
|
|
|
The orange-brown bromine water does not change in color. |
|
|
|
The colorless bromine water becomes orange-brown. |
|
|
|
The orange-brown bromine water becomes colorless. |
