Q. Which of the following is the flame color produced by the Strontium Salt metal ion?
Answer: Crimson Red
Notes: Flame tests are used in analytical chemistry for qualitative identification of certain metal ions. Different metals emit different color flames when heated, due to the excitation of their electrons. This process involves thermal energy, jumping of electrons, and emission of visible light in different colors, connected to the atomic structure. The larger the atom, the lower is the light energy emitted. Strontium Salt, due to its atomic structure, emits a crimson red colored flame.
