Assessment: WAEC SSCE - Chemistry - 2016 (Objective) Subject: Chemistry

Question 1 Report

Which of the following elements would produce coloured ion in agueous solution?
Answer Details
Copper is the element that would produce a colored ion in aqueous solution. Copper ions have a tendency to form complex ions with water or other molecules, which can result in a range of colors depending on the specific ligands involved. For example, copper(II) sulfate forms a blue-colored solution when dissolved in water, while copper(II) chloride forms a green-colored solution. In general, transition metals such as copper are more likely to produce colored ions in solution due to the presence of unpaired electrons in their d orbitals.
