Q: Which of the following ions is colored in solution?
Solution:
Cu2+ ions are colored in solution due to d-d transitions.
Steps: 5
Show Steps
Step 1: Understand that some metal ions can produce color when dissolved in water.
Step 2: Identify that transition metal ions, like Cu2+, often have color due to their electronic structure.
Step 3: Learn about d-d transitions, which are movements of electrons between different energy levels in the d-orbitals of transition metals.
Step 4: Recognize that when light hits these ions, some wavelengths are absorbed, and the remaining light is what we see as color.
Step 5: Conclude that Cu2+ ions are colored in solution because they can undergo d-d transitions.
