Solution — Science definition
Defined in 2 courses:
- A mixture with dissolved particles distributed through a solvent at the particle scale. (Science 6: Matter, Energy & Earth Systems)
- A homogeneous mixture in which one substance is dissolved evenly throughout another, uniform right down to the particle level. (Physical Science: Chemistry)
Where it is taught
- Mixtures, Solutions & Separation — Matter, Mixtures & Water Properties, Science 6: Matter, Energy & Earth Systems, Grade 6
- Solutions & Solubility — Solutions & Dissolved Particles, Physical Science: Chemistry, Grade 11
In use
A solution is a special kind of mixture — one so thoroughly blended that it looks completely uniform, right down to the level of individual particles.
Solutions & Solubility
Questions using solution
Problem 1
Answer and explanation
No. The solute and volume both double, leaving the same ratio under this definition.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 2
- solution: A mixture with dissolved particles distributed through a solvent at the particle scale.
- A dissolved substance has ceased to exist.
- Removing visible particles automatically produces safe pure water.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
solution: A mixture with dissolved particles distributed through a solvent at the particle scale.
A mixture with dissolved particles distributed through a solvent at the particle scale. After removing 3 g sand, 105 g of salt solution remains in the idealized model. After water enters the air, 5 g salt remains. The water is transferred, not destroyed. Real recovery may be incomplete; these assumptions do not show that the liquid was safe to drink.
Problem 3
- the sugar
- the water
- the sweetness
- the glass
Answer and explanation
the water
The solvent does the dissolving and is present in the larger amount — here, the water.
Problem 4
- nonpolar
- unsaturated
- saturated
- dilute
Answer and explanation
saturated
A saturated solution holds all the solute it can at that temperature.
