Character Breakdown

Understanding 溶液 (ようえき)

The word 溶液 refers specifically to a solution in a chemical context, where a solute is dissolved uniformly in a solvent, usually a liquid. It is a technical term commonly used in science, especially chemistry.

Usage and Context

溶液 is often used when discussing concentrations, chemical reactions, or laboratory experiments. It implies a homogeneous mixture at the molecular level.

Common Collocations

  • 溶液の濃度 (ようえきののうど): concentration of the solution — used when measuring or describing how much solute is dissolved.
  • 酸性の溶液 (さんせいのようえき): acidic solution — describes the pH property.
  • アルカリ性の溶液 (あるかりせいのようえき): alkaline solution — another pH-related description.
  • 溶液を混ぜる (ようえきをまぜる): to mix solutions — common in experiments.

Register and Nuance

This word is formal and scientific, rarely used in casual conversation unless discussing science or medicine. Learners should avoid confusing 溶液 with 液体 (えきたい), which means liquid in general, as 溶液 specifically refers to a solution with dissolved substances.

Common Mistake

A frequent learner mistake is to use 溶液 when simply referring to any liquid. Remember, 溶液 always implies a dissolved substance, so use it in scientific or technical contexts.

Example Sentences

このようえきはみずにしおがかんぜんにとけています。

In this solution, salt is completely dissolved in water.

ようえきののうどをせいかくにはかるひつようがあります。

It is necessary to measure the concentration of the solution accurately.

かがくのじっけんで、さんせいのようえきとアルカリせいのようえきをまぜました。

In the chemistry experiment, we mixed an acidic solution and an alkaline solution.
