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.

Flame test would not be useful for analyzing a mixture of metal ions because a mixture of different colors will be observed.

Flame test involves exposing a sample of a metal to flame and observing the color emitted by the flame. Various metals impart various colors to flame which can be used to identify them.

However, in a mixture of metals, a number of colors are observed and no metal can be identified in the mixture.
