What is Flame Test?
A qualitative analytical technique used to detect certain metal ions based on the characteristic color they impart to a flame. When metal ions are heated in a flame, electrons become excited and emit light of characteristic wavelengths. Used to identify alkali and alkaline earth metals.

Flame tests are used in qualitative inorganic analysis to identify alkali metals and alkaline earth metals in solutions and solids. They are a rapid, simple screening test. Flame photometry (instrumental flame test) is used quantitatively for Na, K, Li, and Ca in clinical analysis (serum electrolyte…
Flame tests use an open gas flame. Long hair must be tied back and flammable material kept away. Flame test wires (platinum or nichrome) become hot; allow to cool before touching. Some metal compounds used (barium, lead, thallium) are toxic — avoid ingestion and inhalation of their vapours.
