Flashcards in Flame tests Deck (6):
Why do these metal salts give off a characteristic colour?
Since each element has its own electron configuration this means that each element has different electron transitions and thus characertistic colour
How could you determine what metal is contained in an unknown substance
Hold the salt in the blue flame of the Bunsen Burner and observe the colour given off. Compare this colour with the standard colours given off my different metals
How would you prevent cross contamination?
Use a new disposable wooden splint for each salt tested
Why is a damp wooden splint used to hold the salt?
It does not give off a colour that would interfere with the characteristic colour emitted by the salt
Give one practical application of flame tests
To identify the presence of certain metals
