What characteristic flame color is produced by Sodium salts during a flame test?
Answer and explanation
Correct answer: D. Golden yellow
- Step 1: In flame tests, thermal energy excites valence electrons to higher energy levels. Step 2. When Sodium's 3p electron falls back to 3s, it emits photons at 589 nm, producing an intense golden yellow flame. Answer: Golden yellow. Why not the others: Lilac/violet is Potassium; Brick red is Calcium; Apple green is Barium.
