Question Answer
Carbonate Ions Add HCl and CO2 is given off
Halide Ions Add silver nitrate and nitric acid and a precipitate is formed
Ammonium Ions NaOH and heat, test to see if gas is ammonia
Carboxylic acid Add sodium carbonate and bubbles of gas form
Sulphate ions Add barium chloride and get a white precipitate
Ammonium compounds Test with red litmus paper and goes blue
Phenol Add iron(III) chloride and purple colour forms
Haloalkane Warm with aqueous NaOH, add nitric acid and silver nitrate and precipitate is formed
Alkenes Bromine water is decolourised
Aldehydes Add Tollens' reagent, warm and a silver mirror is formed - Add Fehling's reagent, warm and blue solution goes to a red precipitate
Alcohol Acidified potassium dichromate and changes colour from orange to green
Nitrate ions Add NaOH and Devrada's alloy and ammonia gas is given off
