***HOW DO YOU MAKE WATER WITH OTHER CHEMICALS!?!***
« on: May 12, 2005, 01:11:55 PM »
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

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

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:
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

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

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' :(
