Vedclass · Answer

(D) When aluminium reacts with dilute hydrochloric acid, it forms aluminium chloride and releases hydrogen gas:$2 Al_{(s)} + 6 HCl_{(aq)} \longrightarrow 2 AlCl_{3(aq)} + 3 H_2 \uparrow$Similarly, aluminium reacts with aqueous alkali to release hydrogen gas:$2 Al_{(s)} + 2 NaOH_{(aq)} + 6 H_2O_{(l)} \longrightarrow 2 Na[Al(OH)_4]_{(aq)} + 3 H_2 \uparrow$Thus, both gases $A$ and $B$ are $H_2$.

Aluminium reacts with dilute $HCl$ and liberates a gas '$A$' and with aqueous alkali liberates a gas '$B$'. $A$ and $B$ respectively are
