Which of the following ions can be detected using flame tests?

Step 1: Understand what a flame test is. A flame test is a simple experiment used to identify the presence of certain metal ions based on the color they produce when heated in a flame.
Step 2: Identify the metal ions that can be tested. Common metal ions that can be detected using flame tests include sodium (which produces a yellow flame), calcium (which produces an orange-red flame), and barium (which produces a green flame).
Step 3: Prepare the sample. Take a small amount of the metal salt you want to test and place it on a clean wire loop or a wooden stick.
Step 4: Heat the sample in a flame. Hold the wire loop or stick in the flame of a Bunsen burner or a lighter until it glows.
Step 5: Observe the color of the flame. Look at the color produced by the flame when the sample is heated. Compare the color to known standards to identify the metal ion.
