Options:
Cu2+
Fe2+
Ni2+
Co2+
Correct Answer: Co2+
Solution:
Co2+ ions typically impart a green color to solutions due to d-d transitions.

Questions & Step-by-Step Solutions
Which of the following ions is responsible for the green color of a solution?
Step 1: Understand that ions are charged particles that can affect the color of a solution.
Step 2: Learn that certain ions can absorb specific wavelengths of light, which can result in a color change.
Step 3: Identify that Co2+ (cobalt ions) are known to produce a green color in solutions.
Step 4: Recognize that the green color comes from a process called d-d transitions, where electrons in the ion move between energy levels when they absorb light.
