Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
the color of the flame produced when you burn rubidium is tha same color OS what potassium produce-the colour violet
Alkynes do not produce a specific color in a flame test. Unlike some other elements and compounds which give characteristic flame colors, alkynes do not exhibit a noticeable color when subjected to a flame test.
Potassium has a violet color in the flame test.
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Strontium burns with a bright red color in a flame test.
Cesium burns with a lilac or bluish-violet flame in a flame test.
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
Orangish yellow
Sodium chloride (NaCl) does not have a characteristic color when exposed to a flame test. Sodium compounds are usually identified by the strong yellow color they produce in a flame test due to the sodium ion.
A pink color from the spectral lines of lithium.
In qualitative analysis, flame tests are used in confirming what kind of metal is present in a solution. The green flame or bluish-green flame color is usually present whenever copper metal is present in a solution.
Because some elements or compounds burn the same color
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
To identify the presence of certain metal ions, such as sodium and caesium.
The flame test for strontium - a strong red color.
