Introduction- This experiment is for qualitative analysis so we are trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand.…
