# Can i use deionized water instead of distilled water

My question is really simple : can i use deionized water instead of distilled in experience ?
Because i have a air dehumidifier at home and it produce a lot of deionized water

I know that deionized water ($\ce{diH2O}$) is :

Water that has had almost all of its mineral ions removed, such as cations like sodium, calcium, iron, and copper, and anions such as chloride and sulfate.

And distilled water ($\ce{dH2O}$) is :

Water boiled and then condensed into a clean container, leaving solid contaminants behind

So basically the difference between $\ce{diH2O}$ and $\ce{dH2O}$ is that $\ce{dH2O}$ keep his ions mineral right ?
Can i use deionized water anyway ? Or not ?

• No, distilled H2O does not keep its mineral ions. Whether or not you can use deionized water depends on your application. Mar 3, 2017 at 8:26
• @Ivan Neretin I need water to wash products (like crystal), and to use as reactant Mar 3, 2017 at 8:31
