Vedclass · Answer

(D) Washing soda is sodium carbonate $(Na_2CO_3)$,which in water undergoes hydrolysis to form a basic solution of sodium hydroxide $(NaOH)$.$Al$ is an amphoteric metal that reacts with strong bases like $NaOH$ to form soluble sodium aluminate $(Na[Al(OH)_4])$ and releases hydrogen gas.$2Al(s) + 2NaOH(aq) + 6H_2O(l) \rightarrow 2Na[Al(OH)_4](aq) + 3H_2(g)$.Therefore,washing soda corrodes aluminium vessels.

List-$I$	List-$II$

$(b)$ $Be(OH)_{2}$	$(ii)$ Basic
$(c)$ $Ca(OH)_{2}$	$(iii)$ Amphoteric
$(d)$ $B(OH)_{3}$
$(e)$ $Al(OH)_{3}$

$Al$ vessels should not be cleaned with materials containing washing soda because .............
