Question

what happens when metals react with bases

Answer 1

metal+alkali base-------->metal salt+hydrogen gas

bases only react with zinc and aluminium

Zn+NaOH--------->Na2ZNO3+H2

HOPE IT HELPS PLEASE MARK OT AS BRAINLIEST :)

Answer 2

Not all metals react with bases.
Best metals which react with bases are aluminium and zinc.

The metals react with bases to form salt and liberate hydrogen gas.

2NaOH + Zn -----> Na2ZnO2 + H2.

NaOH + Al -----> NaAlO2 + H2.

This is similar to the reaction of acids with metals.
