    Solution:

    Aluminum vessel do not react with water because when aluminum comes in contact with water, a protective later of aluminum hydroxide is instantly formed on the aluminum surface. 

    2Al+6H2O2Al(OH)3+3H2

    Aluminum hydroxide is amphoteric and it reacts with washing soda to form sodium aluminate which is water-soluble.
    Al(OH)3+NaOHNa[Al(OH)4]Sodium aluminate-water soluble
