Vaporization of mineral water
vaporization of a mineral water, some whitish compounds form in the
container: these are minerals
During vaporization water changes of state but minerals keep their
solid state and they form crystals
In which cases can a vaporization be useful ?
vaporization can be used to recover the solid compounds dissolved in
water since they are not vaporized but they return to their original
Example: In the salt marshes, vaporization is used to recover the salt
contained in seawater.
We can therefore use the vaporization in order to get solid compounds
dissolved in water like salt, minerals, sugar etc.
What is pure water ?
the vaporisation reveals the presence of minerals, it means that water
is not pure.
In chemistry we say that a substance is pure if hasn't been mixed with
If water is mixed with mineral salts it is therefore no longer pure.
It should not be confused pure water with potable water. A potable
water is a water which consumption does not represent a health risk and
this does not preclude the presence of minerals that are even essential
to human body.
