Question

Quizplus · Accepted Answer

The more basic substance will be the one that can donate hydroxide ions (OH-). The presence of an additional oxygen atom in Tl₂O O₃ will make it a weaker base as the oxygen will attract electrons and reduce the ability of the substance to donate hydroxide ions. Therefore, Tl₂O will be the stronger base.
