Success Criteria:
You will show your learning by...
Required practical 7 - identifying ions (AT skills 1,8)
Sulfate ions in solution produce a white precipitate with barium chloride solution in the presence of dilute hydrochloric acid.
Sodium hydroxide solution can be used to identify some metal ions (cations).
Solutions of aluminium, calcium and magnesium ions form white precipitates when sodium hydroxide solution is added but only the aluminium hydroxide precipitate dissolves in excess sodium hydroxide solution.
Solutions of copper(II), iron(II) and iron(III) ions form coloured precipitates when sodium hydroxide solution is added. Copper(II) forms a blue precipitate, iron(II) a green precipitate and iron(III) a brown precipitate.
Students should be able to write balanced equations for the reactions to produce the insoluble hydroxides.
Students are not expected to write equations for the production of sodium aluminate.
Flame emission spectroscopy is an example of an instrumental method used to analyse metal ions in solutions.
The sample is put into a flame and the light given out is passed through a spectroscope. The output is a line spectrum that can be analysed to identify the metal ions in the solution and measure their concentrations.
Students should be able to interpret an instrumental result given appropriate data in chart or tabular form, when accompanied by a reference set in the same form, limited to flame emission spectroscopy.

AFL/Key Questions:
What do Sulfate ions in solution produce when they react with barium chloride in the presence of hydrochloric acid?
Sulfate ions in solution produce a white precipitate with barium chloride solution in the presence of dilute hydrochloric acid.
What solution can be used to identify some some metal ions (cations)?
Sodium hydroxide solution can be used to identify some metal ions (cations).
What do solutions of aluminium, calcium and magnesium ions form?

What happens when sodium hydroxide is added to Solutions of copper(II), iron(II) and iron(III) ions?
Solutions of copper(II), iron(II) and iron(III) ions form coloured precipitates when sodium hydroxide solution is added. Copper(II) forms a blue precipitate, iron(II) a green precipitate and iron(III) a brown precipitate.
