Would flame tests be useful for detecting metal ions present in a mixture of metal ions? explain.

Flame test would be useful for detecting metal ions because each metal ion has its own properties, and when there are many metal ions we can distinguish each metal ion by using or performing flame test.

As in flame test we can distinguish metal ions by there different colors of flames and the color of flames also depends on the temperature factor. And also not all metal ions gives colored flames so sometimes we failed to detect metal ions that are present in a mixture and if there is a very small quantity of metal ions are in a mixture, that is also a problem to detect that.
