Answer
Barium Acetate Dissociation in Aqueous Solution: Ion Identification
This chemical process involves the neutralization of acetic acid (CH3COOH) by barium hydroxide (Ba(OH)2). When two moles of acetic acid react with one mole of barium hydroxide, the products are barium acetate and water. The balanced equation is:
2 CH₃COOH + Ba(OH)₂ → Ba(CH₃COO)₂ + 2 H₂O
🔍 Dissociation of Barium Acetate
Once formed, barium acetate (Ba(CH3COO)2) dissolves in water and dissociates into its ions:
- Cation: Ba2+ (aq)
- Anion: CH3COO− (aq), also known as acetate ion
📘 Ionic Representation and Notes
The barium ion, Ba2+ (aq), is correctly listed in the options. For the anion, although CH3COO− is the accurate formula, the answer choices may include C2H2O2− — which seems to be a typographical representation of acetate. The proper molecular formula for acetate is C2H3O2−, not C2H2O2−.
Other answer options such as OH− or C2O42− do not represent the correct anion for this reaction and are therefore incorrect in this context.
✅ Final Selections
The ions present in aqueous solution after this neutralization reaction are:
- Cation: Ba2+ (aq)
- Anion: CH3COO− (aq) — or the analogous choice C2H2O2− (aq), if assumed to be a typographical error
