You are provided with two containers made up of copper and aluminium. You are also provided with solutions of dilute HCl, dilute HNO3, ZnCl2 and H2O. In which of the above containers these solutions can be kept?

The solutions of dilute HCl, dilute HNO3, ZnCl2 and H2O can be kept in a copper container because copper is a noble metal that does not react with HCl or even HNO3.
If we keep the solution in an aluminium container, aluminium reacts with acids to form Zinc chloride.
Water can be stored in either copper or aluminium as they both do not react with copper.
