==Key Stage 3==
An [[insoluble]] [[material]] is one that cannot be easily [[dissolve]]d in [[water]].
===About Insoluble Materials===
: [[Insoluble]] is the opposite of [[soluble]].
: When an [[insoluble]] [[material]] is put in a [[solvent]] (usually [[water]]) it can still be seen, no matter how much you stir the [[solvent]].
: An [[insoluble]] [[material]] will make the [[solvent]] appear cloudy.
: Many [[material]]s are [[soluble]] in some [[solvent]]s and [[insoluble]] in other [[solvent]]s.
: Many [[material]]s we call [[insoluble]] can [[dissolve]] in a [[solvent]] a small amount but so little that the rest sinks to the bottom of the [[solvent]] to form a [[sediment]].
