There are defiantly some morons here who can not solve equations

2 Al(s) + 6 NaOH(aq) → 3 H2(g) + 2 Na3AlO3(aq)

It is a solution, so no H2O is added

@MrMarcopolo12 well you need a solvent ;)

[meanman90000]

Wait soadium hydroxide us flammable or is that just the aluminium

[mV33rs]

@meanman90000 the sodiumhydroxide in solution and aluminium creates a gas which is flammable hydrogen.

The HCl and Aluminum method is much quicker.

[mV33rs]

but you need HCl for it xD

[Fonta1984]

Correct equation is:

Al(s) + NaOH(aq) + 3 H2O --> NaAl(OH)4(aq) + 3/2 H2(g)

With HCl:

Al(s) + 3 HCl --> AlCl3(aq) + 3/2 H2(g)

So you'll need 3 times more HCl, also your gas will be contaminated by acidic vapors, and i think you don't really want it.

With NaOH the reaction is fast as well. It requires only a little heating at the beginning just to break the thin oxide layer on the Al, after that is self sustaining.

@mV33rs it same cost in aus 6$ hci used for cleaning concreat or $9 for sodiumhydroxide drain cleaner

by volum they work out same

@MrMarcopolo12

Who's being defiant, you or the morons?

[MrMarcopolo12]

@mV33rs

yes I understand. I mean in the equation, in such solution, you do not have to mention the H2O.
