Is it sufficient to identify a cation on a flame test?
It is not suffiecient to identify a cation only on a flame test.æ You must also identify the color of the flame which corresponds to a certain element.
What device may eliminate the inaccuracy of using only flame color to identify an element?
This is a spectrometer.
How can a flame test be used to determine the identity of an element?
Some flame colours are characteristic of metals present, eg Lilac for K+, Red for strontium. However, this is only indicative, because there are a few at least that have a red colour, so it needs to be proven further with a chemical test

when is flame test used?
to identify an unknown sample by its emission spectrum

What color does the element Mg impart to the flame?
The flame test is not used to detect magnesium; a magnesium oxide rod is used as a support for the solutions of other elements in the flame test.
Why is the flame test used?
To identify the presence of certain metal ions, such as sodium and caesium.
