Question 1

What is a flame photometer

Answer 1

Device used in inorganic analysis
Can be used to identify or determine the conc of metal ions

Question 2

How can a flame photometer be used to identify metal ions

Answer 2

Emission spectrum is produced by the flame photometer
Each metal ion produces a unique spectrum so comparing the unknown spectrum to reference spectra can identify the ion

Question 3

How can a flame photometer be used to determine the concentration of metal ions

Answer 3

Take readings using a flame photometer of the metal ions at different concentrations
Plot a calibration curve
Take reading of the unknown sample and compare to curve

Question 4

What is a major advantage of flame photometer compared to simple flame testing

Answer 4

Flame photometry can be used to analyse mixture of ions
Flame test only used to identify one ion at a time
