Match the flame colours of the alkaline earth metal salts in the Bunsen burner
$\begin{array}{l|l}<br />\hline \text{A. Caicium} & \text{p. Brick red} \\<br />\hline \text{B. Strontium} & \text{q. Apple green} \\<br />\hline \text{C. Barium} & \text{r. Crimson} \\<br />\hline<br />\end{array}$
$\begin{array}{l|l}<br />\hline \text{A. Caicium} & \text{p. Brick red} \\<br />\hline \text{B. Strontium} & \text{q. Apple green} \\<br />\hline \text{C. Barium} & \text{r. Crimson} \\<br />\hline<br />\end{array}$
- Correct answerAp, r, q
- Br, p, q
- Cq, r, p
- Dp, q, r
Solution
Flame colours are produced from the movement of the electrons in the metal ions present in the compounds.
Calcium gives brick red colour. Strontium gives crimson colour. Barium gives apple green colour.
Hence, the correct answer is option: 'A'.
