In an aqueous solution of ammonium acetate (NH4C2H3O2), the major ionic species can be identified by considering the dissociation of the compound into its constituent ions.
NH4C2H3O2 dissociates in water into:
- NH4+ (ammonium ion)
- C2H3O2– (acetate ion)
Therefore, the major ionic species present in this solution are NH4+ and C2H3O2–. This means the correct answer is:
Answer: d) NH4+ and C2H3O2–
To summarize:
- NH4+: This is a positively charged ion derived from ammonium.
- C2H3O2–: This is the negatively charged acetate ion.
Each of these ions plays a significant role in the properties and reactions of the solution, including its conductivity and acidity/basicity.
