De-ionizing water

Hi all,

Does anybody know of a simple way to de-ionized water? What I mean by
simple is, can be done at home.

TIA,
Lurch

the water faucet.

Thanks everyone!

If the experiment calls for de-ionized water, then do you think that I can
just substitute distilled? Really, these are just freshman college
chemistry experiments.

TIA,
Charlie

What is the experiment? You may need to think about
the appropriateness of doing them at home.
Many are intended to be done in a lab only.
They may require a proper hood !! For most freshman labs,
distilled water is good enough.

Where the "distilled water" in the grocery stores is just deionized
water, only called distilled water for historical reasons and because
Jenny Johnson wouldn't buy something devilish called "deionized water"
to fill her iron.

Distilled water is usually purer than deionized. Deionized often just has
the hardness ions (Ca, Mg, etc) removed, and sodium is substituted.

For your experiments, rain water is likely to be good enough.

The last bit is called "softening", not deionizing. Deionizing means you
have fewer, not different, ions. Exchanging sodium for calcium and
magnesium is called softening.

An exchange medium *is* used to pull this trick off, but the medium is
regenerated a different way.

Yes, distilled water would be fine.
