Makes damp starch iodide paper turn blue black. 4 of 21 Fluoride Sodium nitrate makes no precipitate 5 of 21 Chloride Sodium nitrate makes white precipitate 6 of 21 Bromide Sodium nitrate makes very pale cream precipitate 7 of 21 Iodide Sodium nitrate very pale yellow precipitate 8 of 21 Lithium Turns red in flame 9 of 21 Sodium Turns orange in flame 10 of 21 Potassium Turns lilac in flame 11 of 21 Calcium Turns yellow red in flame 12 of 21 Copper Turns green blue in flame 13 of 21 Aluminium Sodium hydroxide produces a white precipitate and when excess sodium hydroxide is added the aluminium hydroxide precipitate dissolves 14 of 21 Calcium Sodium hydroxide produces a white precipitate and when there's more there is no change 15 of 21 Magnesium Sodium hydroxide produces a white precipitate and when there's more there is no change 16 of 21 Copper (II) Sodium hydroxide produces a blue precipitate 17 of 21 Iron (II) Sodium hydroxide produces a green precipitate 18 of 21 Iron (III) Sodium hydroxide produces a brown precipitate 19 of 21 Sulfate ions Solution being tested added to dilute hydrochloric acid and few drops of barium chloride are added and a white precipitate is formed if positive 20 of 21 Carbonate ions Detected when acids are added. Carbon dioxide bubbles if present. Lime water goes from clear to milky when carbon dioxide is bubbled through. 21 of 21
