Yes, leaving water out overnight can remove chlorine. Chlorine, a common disinfectant used in public water supplies, evaporates naturally over time when exposed to air. By leaving water in an open container overnight, the chlorine dissipates, potentially improving the taste for those sensitive to it. For better results, use a wide container to increase the surface area exposed to air.
