Three test tubes containing (left to right) precipitate of copper hydroxide, precipitate of iron (III) hydroxide and precipitate of iron (II) hydroxide. The precipitates were made by adding a solution of sodium hydroxide to tubes containing Cu2+, Fe3+ and Fe2+ ions in solution, respectively. This testing for ions practical features in GCSE Chemistry exams.
