Question

Give the reaction of Aluminium and Potassium hydroxide.

Answer 1

The reaction of Aluminium and Potassium hydroxide:

1. Aluminium$\left(\mathrm{Al}\right)$ reacts with Potassium hydroxide$\left(\mathrm{KOH}\right)$ in presence of water to form Potassium aluminate.
2. This reaction is a complex reaction because of the formation of complex Potassium Aluminate (tetrahydroxoaluminate(III)).
3. $\underset{\mathrm{Aluminium}}{2\mathrm{Al}\left(\mathrm{s}\right)}+\underset{\mathrm{Potassium}\mathrm{hydroxide}}{2\mathrm{KOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\underset{\underset{\mathrm{Potassium}\mathrm{aluminate}}{\mathrm{or}}}{\mathrm{Tetrahydroxoaluminate}\left(\mathrm{III}\right)}}{2\mathrm{K}\left[\mathrm{Al}{\left(\mathrm{OH}\right)}_4\right]\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}}{3{\mathrm{H}}_2\left(\mathrm{g}\right)}$
