Determination of the concentration of potassium ion using ...

BACKGROUND. The aim of the experiment is to determine concentration of potassium ion using Flame Photometry (atomic emission spectrometry). Flame photometry is also known as atomic emission spectrometry. When a solution containing cations of sodium and potassium is spayed into flame, the solvent evaporates and ions are converted into their atomic state.
