The correct name for [Al(H₂O)₂(OH^-)₄]^- is ________. A)diwaterquatrahydroxyaluminum B)tetrahydroxydiaquaaluminum (III) C)diaquatetrahydroxoaluminate D)aluminum (IV)hydroxide dihydrate E)aluminumdihydratetetrahydroxide

Question

Quizplus · Accepted Answer

The given compound contains a complex ion in which Al is surrounded by four hydroxyl groups (tetrahydroxo) and two aqua ligands (diaqua). The overall charge on the complex ion is -1, so it must be balanced by a counterion, which is a monovalent anion (^-). Thus, the correct name is diaquatetrahydroxoaluminate. None of the other answer choices accurately reflects the composition or charge of the complex ion.
