Match the elements given in Column-I with the colour they impart to the flame given in Column-II.
List - I | List - II |
|---|---|
(A) Ca | (P) Apple green |
(B) K | (Q) Violet |
(C) Sr | (R) Crimson red |
(D) Ba | (S) Brick Red |
Options:
Answer:
A
Solution:
Calcium (Ca) gives brick red flame, Potassium (K) gives violet (lilac) flame, Strontium (Sr) gives crimson red flame, and Barium (Ba) gives apple green flame. These colours are due to excitation of outer electrons in flame and emission of visible light. Hence the correct matching is A → S, B → Q, C → R, D → P.
