Testing
To test whether the hydrocarbon is unsaturated you should use the Bromine test. To carry out the Bromine test you should add bromine water. If the bromine water becomes decolourised (Goes colorless) then it is unsaturated. Mix water with saturated hydrocarbon as well as unsaturated hydrocarbon. Add some common salt to it. Unsaturated hydrocarbon with water makes salt dissolve and vice versa with saturated hydrocarbon.

Famous quotes containing the word testing:
“Today so much rebellion is aimless and demoralizing precisely because children have no values to challenge. Teenage rebellion is a testing process in which young people try out various values in order to make them their own. But during those years of trial, error, embarrassment, a child needs family standards to fall back on, reliable habits of thought and feeling that provide security and protection.”
—Neil Kurshan (20th century)
“Now I see that going out into the testing ground of men it is the tongue and not the deed that wins the day.”
—Sophocles (497–406/5 B.C.)
“Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
—John Michael Hayes (b.1919)
