Which of the following ions can be detected using a colorimetric method?

Step 1: Understand what a colorimetric method is. It is a technique used to determine the concentration of colored compounds in a solution.
Step 2: Identify the ions that can form colored complexes with specific reagents. For example, iron ions can react with certain chemicals to produce a color change.
Step 3: Recognize that not all ions can be detected this way. Only those that form colored complexes can be measured using colorimetric methods.
Step 4: Conclude that iron is one of the ions that can be detected using this method because it forms colored complexes.
