Give systematic names for the following compounds: (f) (NH₄)₂SO₄

검증된 단계별 안내

Identify the cation and anion in the compound. The cation is NH_4^+ (ammonium) and the anion is SO_4^{2-} (sulfate).

Recognize that NH_4^+ is the ammonium ion, a common polyatomic ion.

Recognize that SO_4^{2-} is the sulfate ion, another common polyatomic ion.

Combine the names of the cation and anion to form the systematic name of the compound.

The systematic name of (NH_4)_2SO_4 is ammonium sulfate.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Ionic Compounds

Ionic compounds are formed from the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions). In the case of ammonium sulfate, (NH4)2SO4, ammonium (NH4+) acts as the cation, while sulfate (SO4^2-) is the anion. Understanding the nature of these ions is crucial for naming and identifying ionic compounds.

Nomenclature Rules

The systematic naming of chemical compounds follows specific nomenclature rules established by the International Union of Pure and Applied Chemistry (IUPAC). For ionic compounds, the cation is named first followed by the anion. In ammonium sulfate, the name reflects the cation 'ammonium' and the anion 'sulfate', which is essential for correctly identifying the compound.

Polyatomic Ions

Polyatomic ions are ions composed of two or more atoms that are covalently bonded and carry a net charge. In ammonium sulfate, the ammonium ion (NH4+) and the sulfate ion (SO4^2-) are both polyatomic ions. Recognizing these ions is vital for understanding the structure and naming of compounds that contain them.
