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.$2Al + 2NaOH + 6H_2O \rightarrow 2Na[Al(OH)_4] + 3H_2(g)$.Therefore,washing soda corrodes aluminum utensils by forming soluble aluminates.
