De-ionized Water:
Deionized Water (We call it "DI water" in the chemistry labs) is just what it sounds like: Water that has the ions removed. Tap water is usually full of ions from the soil (Na+, Ca2+), from the pipes (Fe2+, Cu+), and other sources. Water is deionized by using an ion exchange process.

Why deionize water?

Often, when you are doing chemistry experiments, the ions in water will be an interference. They can switch places with other ions you may be interested in experimenting on. You may also be interested in finding out what elements are in a small sample of material. For example, a farmer may want to know what's in his soil, or the Enviornmental Protection Agency wants to know what a factory's emitting into the air. Dissolving the sample in water and doing tests on the resut is a common technique, and contaminants in the water will make the whole test give the wrong answers. Water with ions in it is also quite a lot more electrically conductive than water without ions in it. If you boil water with lots of ions in it unitl all the water's gone, you'll have a crusty salt residue in your pot.
