Is there a Chemistry nutt here?

[Farrah Day]

Just to confirm what Toady says.

Water readily absorbs gases from the air, which is why pure water is very hard to come by.  Gas molecules from air are effectively suspended between water molecules and as such generally do not chemically react with the water molecules themselves to form new compounds.

Fish breathe oxygen (O2) from the atmosphere that has dissolved in water. Fish do not dissociate H2O to breathe the oxygen component. 

Bubbling air through water (as in a fish tank) will maintain an oxygen rich environment - hence fish can breathe.

Hope that helps.

I have a BS in chemistry and know that a very,very,very small amount of hydrogen will dissolve in water depending on temperature and pressure .The second is made (H2O2)can be made by running an electric current(how much-I don't know) through a sulfuric acid/water solution.The current drives a hydrogen atom off so you see H2 coming off in the form of bubbles leaving HSO4(-) behind which reacts with the remaining water to form H2O2.There is more than one way to make H2O2.Triffid

I do not see how enough hydrogen could be dissolved in water to make any kind of difference.It just doesn't stay around long enough to be very useful.Triffid

You need to know that a 90% pure solution of H2O2 is considered rocket fuel.What you buy in the stores in a brown bottle is only 3%.Triffid
