placed in boiling tube, Hcl added, tube bubbles through limewater, fizzes and turns milky, carbon dioxide produced
distinguish between carbonate and hydrogencarbonate ions
magnesium sulfate forms in the carbonate as magnesium carbonate is insoluble in water
nitrate ions
iron ii sulphate added, concentrated sulfuric acid added down the side, layers separate with brown ring at junction
phosphate ions
ammonium kilt date added, concentrated nitric acid added, placed in warm water, yellow precipitate
