In a flame test experiment, Sodium gives the brightest and most persistent colour in the flame. Do you think that Potassium could be detected visually in the presence of Sodium, by heating this mixture in a flame? Explain your answer.

MissPhiladelphia

Potassium is often not observed during the flame test due to the high intensity of yellow color of Sodium. Its color is violet and is often seen very minimal at the tip of the flame.

Answer:

Yes.

Explanation:

The sodium emission is a doublet at 588.9950 and 589.5924 nanometers,witch is basicaly yellow. (Color wheel with wavelength attached) On the other hand Potassium emmits light at several wavelengths, giving the flame a lilac color.

A picture of both elements emission lines is attached, so you can visualise their difference in light emession.
