Lesson details
Lesson outcome
I can identify metal ions based on the colour of their flame tests and understand how instrumental analysis methods are used for detecting and identifying elements.
Show transcript
Positive ions burn with distinct colours that are visible when heated above a blue Bunsen flame.
Instrumental methods are accurate, sensitive, and rapid for detecting and identifying elements and compounds.
Unique flame emission spectra are produced for each positive metal ion.
A spectrometer can split light from coloured flames into flame emission spectra.
A spectrometer can measure more than one metal ion in a single solution and the concentration of each.
