Step 1
Identify the correct ion and flame colour pair
Answer
The flame test is a qualitative analysis to identify the presence of certain metal ions based on the color of the flame produced when the sample is heated. In this question, we need to find which of the options correctly matches an ion with its corresponding flame colour.
- Barium: typically produces a greenish-yellow flame.
- Calcium: produces an orange-red flame.
- Carbonate: as a salt, does not produce a specific flame colour by itself.
- Copper: produces a blue-green flame.
Based on this information, the correct pair is D. Copper with Blue-green.
