Solution
suh-LOO-shuhn
/səˈluːʃən/
A homogeneous mixture of two or more substances, typically a solute dissolved in a solvent; a means of solving a problem or dealing with a difficult situation.
In chemistry, 'solution' implies a uniform mixture at the molecular level. In general usage, it refers to an answer or resolution.
The story behind the word. The word 'solution' comes from the Latin 'solutio,' meaning 'a loosening, unbinding, or dissolving.' This in turn comes from the verb 'solvere,' meaning 'to loosen, unbind, or set free.' In chemistry, a 'solution' is formed when a solute is 'loosened' or 'dissolved' into a solvent. The general meaning of solving a problem also reflects this idea of 'unbinding' or 'resolving' a difficulty.
Word relationships
- Mixture: More general; can be homogeneous or heterogeneous, while a 'solution' is always homogeneous.
- Answer: Refers to the resolution of a problem, not a chemical mixture.
- Problem: A matter or situation regarded as unwelcome or harmful and needing to be dealt with and overcome.
- Suspension: A heterogeneous mixture where solid particles are dispersed in a liquid but will eventually settle out.
Commonly confused with
- Mixture: A 'solution' is a specific type of homogeneous mixture, meaning the components are uniformly distributed. A 'mixture' can be homogeneous or heterogeneous.
Word family
- dissolve (verb): To form a solution with a liquid; to disappear or break up.
- soluble (adjective): Able to be dissolved, especially in water.
Collocations
- aqueous solution
- dilute solution
- concentrated solution
- buffer solution
- find a solution
- perfect solution
Idioms & expressions
- the solution to all problems
Example sentences
- "When sugar completely dissolves in water, it forms a clear, homogeneous solution." Sugar dissolving in water forms a solution.
- "After weeks of deliberation, the team finally arrived at a viable solution for the complex engineering challenge." Finding a solution to a problem.
Memory hook
Think of a 'solution' as 'loosening' a problem or 'dissolving' a substance. Loosen/dissolve
When not to use
Do not use 'solution' in a chemical context if the mixture is heterogeneous (e.g., a suspension or colloid).
Fun facts
- The 'universal solvent' is water, due to its polarity, which allows it to dissolve many different substances.
- Not all solutions are liquid; alloys like brass (copper and zinc) are solid solutions.
