Deionized water is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.

Sure, if you can purchase, install and maintain the necessary equipment. It would probably be cheaper and more convenient to just buy it at the grocery store, however.

 

You may want to add some flavor as with everything removed it would be pretty tasteless.

 

Water that has been run thru a water softener. It is not pure! Distilled water tends to be pure.

 

As usual, well said hontonai.

Producing deionized (DI) water in the home is typically done with an RO system (Reverse Osmosis). It is far superior to using the classic "water softener", albeit more expensive upfront.

In industry we use resin bead tanks (and carbon tanks to remove organics) since they are much higher output that most RO systems. However, these tanks need to be replenished fairly often and are thus costly. In our laboratory, we further process DI water into ultra-high purity, bacteria-free water by using an additional unit.

 

Distilled water is only as good as the system that produces it. It can also contain organics.

 

is distilled water just as good as deionized water for coin bathing after acetone?

 

You DO NOT drink deionized water!

 

ACETONE is evil and toxic.

Distilled water is a good safe coin bath. Do not use tap water.

 

why you say that?

 

Anyone got a water softener? That is pretty much what you are drinking!

 

Evil?!?!?! Toxic - yes, but so are water, salt, 78% of air, etc.

 

Completely deionized water is electrically non-conductive but highly chemically reactive.

 

evil, is my opinion of acetone esp. what it does to remove tone from a coin.
toxic, acetone's effect on the human respiratory and nervous system as well as the environment.

too much of anything is bad, like eating too much iced cream. :eating:

 

Good thing it's not called

dHoH,...ooops

it is isn't it.:secret:

Just my way of saying Homer Simpson would not drink it.

 

liez

 

liez = ???

 

No such thing as too much ice cream....?

 

Try eating a gallon at one sitting... or a Vermonster at Ben & Jerry's...
The saturated fat will getcha!

 

just means you need to run fatbutt RUN! while you carry and eat the gallon or the Vermonster at Ben & Jerry's... :whistle:
