Al liberate $H_{2}$ gas on dissolving it in

Options:

Answer:

Solution:

Aluminium (Al) reacts with both acids like HCl and strong bases like NaOH to liberate hydrogen gas. This amphoteric nature allows it to react with both, as shown in the reactions below.

Reactions:

1. With acid (HCl):

$2 Al (s) + 6 HCl (a q) \to 2 AlCl_{3} (a q) + 3 H_{2} (g)$

2. With base (NaOH):

$2 Al (s) + 2 NaOH (a q) + 6 H_{2} O (l) \to 2 Na [Al (OH)_{4}] (a q) + 3 H_{2} (g)$
