Vedclass · Answer

(C) The reaction of aluminum $(Al)$ with an excess of aqueous sodium hydroxide $(NaOH)$ is a characteristic reaction where aluminum acts as an amphoteric metal. The balanced chemical equation for this reaction is: $2Al(s) + 2NaOH(aq) + 6H_2O(l) \longrightarrow 2Na^{+}[Al(OH)_4]^-(aq) + 3H_2(g)$ In this reaction, $P$ is the complex ion sodium tetrahydroxoaluminate$(III)$, $Na^{+}[Al(OH)_4]^-$, and $Q$ is hydrogen gas, $H_2$. Therefore, the correct option is $C$.

$Al +$ aq. $NaOH$ (excess) $\longrightarrow P + Q$. $P$ and $Q$ are
