==Key Stage 3==
===Meaning===
: A '''solution''' is a [[mixture]] where a [[substance]] (usually a [[solid]]) is [[dissolve]]d in a [[liquid]].
===About Solutions===
: [[Solution]]s are usually made of a [[liquid]] that is known as a [[solvent]] and a [[solid]] which is known as a [[solute]].
: When a [[solute]] [[dissolve]]s in a [[solvent]] it becomes a [[solution]].
: Some [[solution]]s are a [[mixture]] of two [[solvent]]s, for example [[water]] and [[ethanol]].

===Separating Solutions===
: The [[solute]] and [[solvent]] can be [[Separating Mixtures|separated]] by [[distillation]].

|-
| style="height:20px; width:600px; text-align:center;" |This [[diagram]] shows how the [[solute]] and [[solvent]] can be [[Separating Mixtures|separated]] by heating the [[solution]] to [[evaporate]] the [[solvent]] leaving the [[solute]] behind and then [[condensing]] the [[evaporate]]d [[solvent]] by cooling it down and collecting it in a [[Conical Flask|conical flask]].

==Key Stage 4==
===Meaning===
: A '''solution''' is a [[mixture]] where a [[substance]] (usually a [[solid]]) is [[dissolve]]d in a [[liquid]].
===About Solutions===
: [[Solution]]s are usually made of a [[liquid]] that is known as a [[solvent]] and a [[solid]] which is known as a [[solute]].
: When a [[solute]] [[dissolve]]s in a [[solvent]] it becomes a [[solution]].
: Some [[solution]]s are a [[mixture]] of two [[solvent]]s, for example [[water]] and [[ethanol]].
: Some [[gas]]es may also [[dissolve]] in a [[liquid]] to make a [[solution]]. For example; [[Carbon Dioxide]] may [[dissolve]] in [[water]]. This makes the [[water]] [[acid]]ic and is what leads to [[Ocean]] [[acid]]ification if there is too much [[Carbon Dioxide]] in the [[Earth's Atmosphere|atmosphere]]. A 'carbonated' beverage (like cola or lemonade) has [[Carbon Dioxide]] coming out of [[solution]] and creating bubbles. This is what makes the drink 'fizzy'.
