After neutralization i think water remains.
I have remembered about the base when read about francium-rubidium some pages before. After contact with water forms a boom and rubidium hydroxide (alkali).

I hope this will be added in the next or after one version of tpt. I think no one will say that it is useless

EDIT:
+1
So, here is my idea.
Actually it is wall idea, but i don't want to create new topic for this.

What do you think about walls, that will open if pressure higher(lesser) than some number?
So, we can automaticly regulate pressure

Edited! Where are you people?
P.S. Sorry for double post

no... why would we need rubidium hydroxide and hydrogen. we already 'gas' that is flammable and 'acid' witch is essentially the same as a base except for when they mix. and hydrogen and rubidium hydroxide are way to specific to add. If they are, then more people will start to requesting things like carbon dioxide, nitrogen, oxygen and water being released released when Nitroglycerin burns , and other silly element ideas and reactions. Besides sodium hydroxide has been directly denied a place in the PT, so I'm pretty sure it goes with out saying that RbHO should pack its bag and get out of sight...
