Would you store a solution of zinc nitrate in an aluminum container? Use half-reactions to explain your answer.

Question

Al ==> Al^+3 + 3e
Zn ==> Zn^+2 + 2e
Look up the above half reactions and you will see that the Al will go into solution and the Zn+2 will come out. Eventually, enough of the Al container will dissolve to cause a leak in the container.

Answer 1

Therefore, it is not recommended to store a solution of zinc nitrate in an aluminum container.
