What is the reaction of aluminum and sodium hydroxide?
I need to know the reaction of aluminum and sodium hydroxide in the form of a formula? I've been researching this and apparently all the ones I've found are wrong :( so for all of you who can actually figure this out, thanks so much!

- Well, lets see ... Aluminum is Al+ and Sodium Hydroxide is NaOH, which is a strong base, so it dissociates in water as Na+ and OH - ... So, you essentially will have ...
Al+ + Na+ + OH - --> AlOH + Na+
I'm not 100% positive on this, but it makes sense to me! The positive ion has to pair with the negatively charged ion! ... Hope it helps!
- In the presence of water this is a two step process.
2Al + 6H2O = 2Al(OH)3 + 3H2. (Hydrogen actually evolved in the lab.)
Al(OH)3 + NaOH = Na+ + {Al(OH)4}-
