How do you produce water using just other chemicals, having no water to begin with?
ie with hydrogen peroxide? other stuff neutralizing each other?

will a 100% solution of methyl alcohol neutralize an 80% solution of ethyl alcohol to make water? or i dont know what it does

*delete me*

Two simplest things coming to mind are synthesis out of gaseous hydrogen and oxygen and neutralization - for example adding anhydrous acetic acid to sodium hydroxide. Also in some polycondensation reactions water is a byproduct.

No idea what you mean by neutralization in repect to methanol and ethanol. They just mix. Besides, using 80% ethanol you use 20% water.

2NH3 + 3CuO -> 3Cu + 3H2O + N2

geodome's post reminded me of other obvious reaction - reduction of oxides using hydrogen.

How about via Fisher esterification?

alcohol + carboxylic acid --> ester + water

[Grumples]

If you mix barium hydroxide octahydrate with ammonium chloride (both are solids) you get a rather large quantity of very cold water. (cold enough to freeze pure water around the beaker, for instance).

Here is the coolest way to do it. Hydrogen plus oxygen plus flame.  :devil2:

Eeee, this one was already posted. I have just deliberately called it 'synthesis' so that it sounds more seriously

dealing with oxygen directly is dangerous. i would a prefer a metal oxide with higher oxygen mass%.

It must be my English then, metal oxides are part of what I meant by 'oxides'

Thanks guys! You helped a lot!
