WebA flame testis an analytical procedure used in chemistryto detect the presence of certain elements, primarily metalions, based on each element'scharacteristic flame emission spectrum(which may be affected by the presence of chloride ion). The color of flamesin general also depends on temperature and oxygen fed; see flame color. Process[edit] WebAce-K (KC3H4NO4S) contains POTASSIUM ION. Thus, it will give off LILAC color in flame test. Sweet 'N Low [Ca(C7H4NO3S)2] contains CALCIUM ION. Thus, it will give off ORANGE RED COLOR in flame test. Equal R (C14H18N2O5) contains NO METAL ION. Hence, it will NOT GIVE off color like the other two mentioned above.
