Question
Which of the following ions gives coloured solutionCu+Zn++Ag+Fe2+
Solution
The ion that gives a colored solution among Cu+, Zn++, Ag+, and Fe2+ is Fe2+. This is because Fe2+ ions can form complex ions with water in solution, which absorb light in the visible region and hence appear colored. The specific color can vary depending on the exact nature of the complex ion and its oxidation state. The other ions (Cu+, Zn++, and Ag+) typically do not form colored solutions under normal conditions.
