Zinc and aluminium are amphoteric metals, which means that they react with both acids and alkalies to liberate hydrogen gas.
Zn + 2HCl ----> ZnCl2 + H2
Zn + 2NaOH -----> Na2ZnO2 + H2
2Al + 6HCl -----> 2AlCl3 + 3H2
Al + NaOH + H2O ----> NaAlO2 + H2
Verified answer
Zinc and aluminium are amphoteric in nature so they both behave as acid as well as base...
