Q
Q: Which of the following ions can be detected using a flame test that produces a green flame?
Solution: Barium ions produce a green flame during a flame test, while sodium produces a yellow flame, potassium a lilac flame, and calcium an orange-red flame.
Steps: 5
Step 1: Understand what a flame test is. A flame test is a way to identify certain metal ions based on the color of the flame they produce when heated.
Step 2: Know that different metal ions produce different flame colors. For example, sodium produces a yellow flame, potassium produces a lilac flame, and calcium produces an orange-red flame.
Step 3: Identify the specific ion mentioned in the question. The question asks about ions that produce a green flame.
Step 4: Recognize that barium ions are known to produce a green flame during a flame test.
Step 5: Conclude that among the ions listed, barium is the one that produces a green flame.
