NaOH → Na⁺ + OH⁻
a. Acid
b. Base
c. Salt

검증된 단계별 안내

Identify the molecule given: NaOH (sodium hydroxide).

Look at the dissociation products: NaOH dissociates into Na⁺ (sodium ion) and OH⁻ (hydroxide ion).

Recall the definitions: Acids release H⁺ ions in solution, bases release OH⁻ ions, and salts dissociate into ions that are neither H⁺ nor OH⁻.

Since NaOH releases OH⁻ ions upon dissociation, classify it as a base.

Confirm that Na⁺ is a cation from a metal and OH⁻ is the hydroxide ion, which is characteristic of bases.

주요 개념

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

Acids, Bases, and Salts Classification

Acids are substances that release H⁺ ions in solution, bases release OH⁻ ions, and salts are ionic compounds formed from the neutralization of an acid and a base. Understanding these definitions helps classify molecules based on their dissociation products.

Dissociation in Aqueous Solutions

Dissociation refers to the process where molecules separate into ions when dissolved in water. Identifying the ions produced, such as OH⁻ or Na⁺, is key to determining whether the original molecule is an acid, base, or salt.

Role of Hydroxide Ion (OH⁻) in Bases

The presence of hydroxide ions (OH⁻) in the dissociation products indicates a base. For example, NaOH dissociates into Na⁺ and OH⁻, classifying it as a strong base due to the release of OH⁻ ions.
