Answer:

Aluminum is oxidized............

Explanation:

#Al(s) rarr Al^(3+) + 3e^(-)# #(i)#

And hydrogen ion is reduced............

#H^(+) + e^(-) rarr 1/2H_2(g)# #(ii)#

And we can cross multiply the individual redox reactions to remove the electrons, which are conceptual particles, i.e. #(i)+3xx(ii)#:

#Al(s) +3H^(+) rarr Al^(3+) + 3/2H_2(g)#
