Solution
Correct Answer:
Calcium
The Flame Test identifies metal ions based on the characteristic light emitted when their electrons return to lower energy levels after being excited in a flame.
- Calcium (Ca2+): Gives a characteristic Brick-red flame.
- Comparison:
- Sodium (Na+): Golden yellow.
- Potassium (K+): Lilac (Pale violet).
- Barium (Ba2+): Apple-green.
- Strontium (Sr2+): Crimson-red.
- Small amounts of concentrated HCl are used to convert the salt into volatile chlorides for better results.
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.
