| Estimation of Sodium using Flame photometer | Prabha Kishore | 10 Nov 2009 |
sodium, potassium, calcium and lithium and other common elements impart characteristic colours with the bunsen flame. the intensity of the coloured flame varies with the amount of element introduced. this forms the basis of flame photometry.
When a solution containing a compound of the metal to be investigated is aspirated into a flame, the following processes occur.
i) Solvent evaporates leaving behind a solid residue.
ii) Vapourisation of the solid coupled with dissociation into its constit
