c. Salt

검증된 단계별 안내

Identify the molecule given: H₂SO₄ (sulfuric acid).

Look at the dissociation products: 2H⁺ and SO₄²⁻.

Recall that acids are substances that release H⁺ ions (protons) when dissolved in water.

Since H₂SO₄ dissociates to release 2H⁺ ions, it fits the definition of an acid.

Therefore, classify H₂SO₄ as an acid based on its dissociation into hydrogen ions and sulfate ions.

주요 개념

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

Acids and Their Ionization

Acids are molecules that release hydrogen ions (H⁺) when dissolved in water. For example, H₂SO₄ dissociates to produce H⁺ ions, which increase the solution's acidity. Understanding acid ionization helps classify molecules based on their ability to donate protons.

Bases and Their Ionization

Bases are substances that accept hydrogen ions or release hydroxide ions (OH⁻) in solution. Identifying bases involves recognizing molecules that increase OH⁻ concentration or remove H⁺ ions, which raises the pH of the solution.

Salts and Their Formation

Salts are ionic compounds formed from the neutralization reaction between acids and bases. They dissociate into cations and anions that are neither H⁺ nor OH⁻, such as SO₄²⁻ in the example, and do not affect the pH significantly on their own.
