Which of the following metal chlorides does NOT impart any characteristic color to the non-luminous — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Beryllium and Magnesium do not impart any color to the flame due to their very high ionization enthalpies. The energy of the Bunsen flame is insufficient to excite their valence electrons. $Ba$ (apple green), $Sr$ (crimson), and $Cu$ (greenish blue) give distinct colors.
