Solution

The hydroxyl ion (OH⁻) is negatively charged. When water (H₂O) dissociates, it splits into a hydrogen ion (H⁺) and a hydroxyl ion (OH⁻). The hydrogen ion, being simply a proton, has no electrons and carries a positive charge. In contrast, the hydroxyl ion has one oxygen atom and one hydrogen atom, and due to the extra electron that accompanies it, the overall charge is negative. Therefore, in the context of water dissociation, the hydroxyl ion is negatively charged.

Final Answer

The hydroxyl ion is negatively charged.
