If the KOH is in a moderately concentrated aqueous solution, the net reaction can be: 2 Al + 6 H2O => 2 Al(OH)3 + 3 H2. In this instance, the KOH does not undergo any net reaction; instead it catalyzes the reaction between aluminum and water by preventing the solid aluminum from maintaining a passivation layer on its surface.
If the KOH is in a still more concentrated aqueous solution, the reaction can be:
2 Al + 4 KOH => K2Al2O4 + H2.

What type of reaction is Al HCl?
bob and my mom :)
How do you prepare hydrogen in a laboratory?
1. Zn + 2 HCl → ZnCl2 + H22. Treating of aluminum powder with NaOH or KOH solutions.2 Al + 6 H2O + 2 NaOH → 2 NaAl(OH)4 + 3 H2Aluminium2 Al + 6 H2O + 2 OH− → 2 Al(OH)−4 + 3 H2
What is the product of the reaction between aluminum and magnesium?
Al(s) + MgCl2(aq) ==> no reaction or a very slow reaction. The reason being that Mg is more reactive than Al so Al will not readily displace/replace Mg. If the reaction occurs, it will be 2Al(s) + 3MgCl2(aq) ==> 2AlCl3(aq) + 3Mg(s)
What is the word equation for the reaction of iodine with aluminum to make aluminum iodide?
The chemical reaction is the following: 2 Al + 3 I2--------2 AlI3
What is the equation for iron III oxide plus aluminum yields aluminum oxide and iron?
Fe2O3 + 2Al --> Al2O3 +2 Fe The reaction is commonly known as thermite for the enormous amount of heat produced. The iron produced by the reaction is molten.
