The barium and copper metal elements produce similar flame colors as well. The barium and copper elements both yield a green-colored flame although it is interesting to note that barium tends to make paler green flames that do not persist for a very long time. A flame test is therefore not...
Of the metal ions tested of an example experiment, sodium produces was the brightest and most persistent color in the flame. Could potassium be detected visually in the presence of sodium by burning t Which one of the following statements is TRUE regarding flame t...
What flame test color would be produced for the compound salt substitute with its active ingredient {eq}KCl {/eq}? Flame Test: Flame test is a qualitative test used to identify the presence of specific metal ions. The gas or vapor particles of the me...
Flame photometry of calcium, an inherently simpler method, tends to be inaccurate when applied to serum and even more so with urine because ofinterference from both cations and anions(5- 7). Sodium, potassium, and phosphate produce the chief problems. ...
