Flame Tests
The flame test is a procedure used in chemistry to detect the presence of certain metal ions, based on each element's characteristic
emission spectrum. The color of flames
in general also depends
on temperature.
The flame test is fast and easy to perform, and does not require any equipment not
usually found in a chemistry laboratory. However, the range of detected elements is small, and the test relies on the
subjective
experience of the experimenter rather than
any objective measurements.
