用法筆記

In chemistry, 'a solution' always refers to a homogeneous mixture. The substance that dissolves is called the 'solute' and the liquid it dissolves into is called the 'solvent'. This sense is uncountable when referring to the state of being dissolved (e.g. 'in solution').

常見錯誤

❌I made a sugar solution by mixing sugar in water without stirring.
✅I made a sugar solution by stirring sugar into warm water until it dissolved.
💡A solution requires the substance to be fully dissolved, not just mixed.

文法句型

用法筆記

This sense is almost always used in technical or scientific writing. In everyday English, speakers prefer the verb 'dissolve' or the phrase 'dissolving process' instead of the noun 'solution' for this meaning.

常見錯誤

❌The solution of sugar in water makes sweet water.' (when meaning the process)
✅The dissolving of sugar in water produces a sweet liquid.
💡The process sense of 'solution' is formal and rare in everyday speech; use 'dissolving' instead.
