eli5: Why can’t you drink Demineralised Water?

1.26K viewsChemistryOther

At my local hardware store they sell something called “Demineralised Water High Purity” and on the back of the packaging it says something like, “If consumed, rinse out mouth immediately with clean water.”

Why is it dangerous if it’s cleaner water?

Been good responses but the ELI5 is more simple.

Water always has extra stuff in it, mostly stuff that your body needs. Sometimes water has too much of that stuff in it and when the water dries or you wipe it up, a small amount of that stuff gets left behind. That can be bad sometimes anything that boils water or has water running through it can start to gunk up with all that stuff that gets left behind, and start to break. So we invented ways to take all that stuff out of the water so we can use extra clean water for those things. It’s not safe to drink because it’s so clean, it has so little stuff in it, that it acts like a sponge when it touches things and absorbs some stuff from the things it touches. When it touches the inside of your mouth, it takes things out of your body that your body needs, and that can hurt you.
