Chemical Reactions and Equations

Long Answer Type

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?

Copper is a nobel metal. It does not react with hydrochloric acid or with nitric acid. But aluminium is more reactive than copper. So, these acids should be kept in copper container. 

Copper is less reactive than zinc and hence zinc chloride solution can be kept in copper container. But aluminium is more reactive than zinc and hence zinc chloride solution cannot be kept in aluminium container. For keeping water; both the containers can be used. However, copper is better.
