===Meaning===
Produce a [[salt]] from a [[Neutralisation]] [[Chemical Reaction|reaction]] between an [[acid]] and an [[insoluble]] [[base]] then [[Separating Mixtures|separate]] the [[salt]] from the [[mixture]] to obtain a [[pure]] sample.

===Method===
#Add roughly 40ml of 1.0[[Molarity|M]] [[Sulphuric Acid]] to a 100ml [[beaker]].
#Heat the [[acid]] to 90°C.
#Use a [[spatula]] to add a small amount of [[Copper (II) Oxide]] powder to the [[solution]] and stir with a [[Glass Rod|glass rod]].
#Repeat step 3 each time the [[Copper (II) Oxide]] disappears until the some of the powder remains at the bottom despite stirring.
#Allow to cool then pass the mixture through [[Filter Paper|filter paper]] and a [[Funnel|funnel]] into a [[Conical Flask|conical flask]] to remove the [[Copper (II) Oxide]] [[residue]], leaving only the [[solution]] in the [[Conical Flask|conical flask]].
#Pour the [[solution]] into an [[Evaporating Dish|evaporating dish]] and heat gently to [[evaporating|evaporate]] the [[water]] from [[solution]]. This will leave [[pure]] [[Copper Sulphate]] crystals.
