experiment of detection of bromide anion bromide anion is detected in sodium bromide salt by a main experiment and another confirmatory experiment main experiment to sodium bromide salt drops of the group reagent which is the concentrated sulfuric acid what do you observe effervescence takes place due to the evolution of hydrogen bromide gas which is colorless and partially oxidized by the sulfuric acid and orange red fumes of bromine will be separated and increases by heating [Music] and turns a paper wetted we've starch into yellow confirmatory experiment add a small amount of sodium bromide salt to a clean test tube then add distilled water with shaking to form a salt solution then add to it silver nitrate solution what do you observe a white yellowish precipitate is formed of silver bromide [Music] add a concentrated ammonia solution to that precipitate what do you observe the precipitate slowly dissolves in the concentrated ammonia solution summary on adding the concentrated sulfuric acid to sodium bromide salt a reddish orange fumes of bromine are separated and changed a paper wetted with starch into yellow on adding silver nitrate solution to sodium bromide solution a white yellowish precipitate of silver bromide is formed which slowly dissolves in a concentrated ammonia solution
