Which salt produce colour on bunsen burner flame when (salt +HCl conc.) is applied on flame :-
Options:(select one or more)
Answer:
A, B, C
Solution:
CaCO₃ (B): Contains Ca²⁺ ions, which produce a characteristic brick-red flame.
CuSO₄ (C): Contains Cu²⁺ ions, which result in a distinct bluish-green flame.
Mg₃(BO₃)₂ (A): While magnesium itself doesn't color the flame, the borate (BO₃³⁻) ion produces a green flame.
NH₄Cl (D): Ammonium salts are volatile but do not impart any specific color to the flame.
Conclusion: Since A, B, and C all contain ions that color the flame, they are the correct choices.
