Theory behind the flame test

WebbA flame test is a qualitative test used in chemistry to identify a metal from its emission spectrum. A qualitative test doesn’t tell us how much metal is present in a sample. It just gives us an idea of which metals may be present. WebbA typical flame will burn yellow/orange with a little bit of blue near the base of the wick. When you burned the skewer tip coated with sodium chloride, you should have seen that the flame on the sodium chloride was pure yellow/orange (without any blue). This is because when the metal sodium is burned, it makes intense yellow/orange light.
