Q: Which of the following methods can be used to identify cations in a solution?

Solution: All of the listed methods can be employed to identify cations in a solution through various analytical techniques.

Steps: 5

Step 1: Understand what cations are. Cations are positively charged ions that can be found in a solution.
Step 2: Learn about different methods used to identify cations. Common methods include flame tests, precipitation reactions, and spectroscopy.
Step 3: Recognize that each method works differently. For example, flame tests involve heating a sample to see the color produced, while precipitation reactions involve adding a reagent to form a solid.
Step 4: Realize that all the listed methods can be used to identify cations, as they each provide different information about the ions present in the solution.
Step 5: Conclude that using a combination of these methods can give a more accurate identification of cations.
