Identifying metal ions. 1 of 16 What colour does Lithium produce under a flame test? Red 2 of 16 What colour does Sodium produce under a flame test? Yellow 3 of 16 What colour does Potassium produce under a flame test? Lilac 4 of 16 What colour does Calcium produce under a flame test? Red 5 of 16 What colour does Barium produce under a flame test? Green 6 of 16 Aluminium, calcium and magnesium ions form what colour precipitate with what solution? White precipitate with sodium hydroxide solution. 7 of 16 Which hydroxide precipitate then dissolves in excess sodium hydroxide solution? The aluminium hyrdroxide precipitate. 8 of 16 What colour precipitates do Copper(III), Iron(II) and Iron(III) ions make with what solution? Copper forms a blue precipitate, iron(II) a green precipitate and iron(III) a brown precipitate with sodium hydroxide solution. 9 of 16 Carbonates react with what to form carbon dioxide? Dilute acids. 10 of 16 What is the test for carbon dioxide? It turns limewater cloudy. 11 of 16 Halide ions in solution produce precipitates with what solution and in the presence of what dilute acid? Silver nitrate solution with dilute nitric acid. 12 of 16 What is the name of each halide ion and what colour are they? Silver chloride = white, silver bromide = cream and silver iodide = yellow. 13 of 16 Sulfate ions in solution produce what colour precipitate with what solution and in the presence of what dilute acid? White precipitate with barium chloride solution in the presence of dilute hydrochloric acid. 14 of 16 How can the volumes of acid and alkali solutions that react with each other be measured? By titration using a suitable indicator. 15 of 16 If the concentration of one of the reactants is known, the results of the titration can be used to find what? The concentration of the other reactant. 16 of 16
