water. A compound or solution?

Arguing about words is almost always foolish...

Pure water is a compound of Hydrogen and Oxygen.

This means that there is something called a "water" molecule that are all made up of the same combination of the same number of the same type of atoms of the same element.

If you have a bunch of these same type of molecules you will have water.

The word "solution" means that something is dissolved in another substance. There is really no such thing as "pure" water, so water is always a solution (i.e. there are always something dissolved in it).

If you want to get really technical, pure water is also a solution since some of the water molecules dissolve.

So there. You're both right. Sorry to say it, but technically your friend is more right.

Ill just say were both right and forget about the last thing

I like to have a dispute and it turns out there is more than one correct answer.

Additionally, water in an open vessel exposed to our earth atmosphere will always have some gas going into solution into it as well. It's that atmospheric gas in solution that fish depend on to breathe. Fish don't like stagnant water for this reason.

It wouldn't take much time in our present day atmosphere outside of a controlled environment for water to become a bit of a suspension as well as a solution and a compound.

It's also a solvent; no mere liquid.

Do deuterium and tritium dissolve in H20? Or do they actually fraction into layers if poured into the same container? Does anyone know?

I'm not sure but I'm under the impression that they will fraction with the tritium at the bottom and the deuterium in the middle - the H20 at the top each being a molecule of a specific gravity and density. You might have to dissolve a dye into each sample to show that this is so since I believe all three are transparent.

We were discussing water. Why not heavy water?

As I know , water is acompound from 2 H and one O.A solution has one substance dissolved into the other .The one with great amount is called solvent and with the ilttle amount is called solute.Like sugar in water .So , neither hydrogene dissolve into oxgene to make water nor oxgene.They react and combine to make H2O.

It can be either if you argue your point right!
My initial reaction to this question is to say that it is a compound of hydrogen and oxygen, but after asking various family members, it turns out that water is an equilibrium :

OH- <=> H20 <=> H30+

It is a solution of different forms of dihydrogen oxide.

So both of you are right in a way!
