Solution
Correct Answer:
Na+
Sodium salts produce an intense and persistent golden-yellow flame due to strong emission around 589 nm. Potassium gives lilac, calcium gives brick red, and barium gives apple green, so the observed color identifies Na+.
This easy difficulty chemistry question is from the chapter principles related to practical chemistry, covering the topic of flame test. It appeared in the 2025 exam.
