(C) Aluminium reacts with aqueous $NaOH$ to form sodium tetrahydroxoaluminate$(III)$. The reaction is: $2Al(s) + 2NaOH(aq) + 6H_2O(l) \longrightarrow 2Na[Al(OH)_4](aq) + 3H_2(g)$. In aqueous solution, the species exists as the octahedral complex $[Al(H_2O)_2(OH)_4]^-$, where the coordination number of $Al$ is $6$.
