Question

Aluminium ion in solution is an example for

Answer 1

Answer:   The compounds of aluminium are mainly covalent. In ionic compounds, such as aluminum fluoride, it exits as a trivalent aluminum ion, A1 3+. The hydrated aluminum ion is found in many compound e.g. A1 2(SO 4) 3 . 18H 2O, and in aqueous solution Hydrated aluminum ions are usually acidic in aqueous solution.

Explanation:   For example: 1 Ammonium ion: NH 4 + 2 Ion sodium: Na + 3 Ion magnesium: Mg +2 4 Ion aluminum: Al +3 5 Ion chloride: Cl – 6 Ion sulfur: S -2 7 Ion phosphorus: P -3 8 Ion permanganate: MnO 4 – 9 Ion sulfate: SO 4 -2 10 Ion phosphate: PO 4 -3 .
