$Al$

Vedclass · Answer

(B) Sodium hydroxide $(NaOH)$ is a strong base. Most metals do not react with bases,but amphoteric metals like Aluminum $(Al)$,Zinc $(Zn)$,and Lead $(Pb)$ react with strong bases to form complex salts and release hydrogen gas $(H_2)$.For the reaction of Aluminum with sodium hydroxide:$2Al + 2NaOH + 6H_2O \rightarrow 2Na[Al(OH)_4] + 3H_2 \uparrow$Here,$Na[Al(OH)_4]$ is sodium tetrahydroxoaluminate (a salt) and $H_2$ is hydrogen gas. Therefore,$Al$ is the correct metal.

Which of the following metals reacts with sodium hydroxide to produce a salt and $H_2$ gas?
