Can a solution of CrCl3 be stored in an aluminum container?

depend on which metal is more reactive...

aluminium is more reactive than chromium and so it will displace chromium to form AlCl3 solution..thus CrCl3 cannot be stored in aluminium container..

hope that helps

No, it is not recommended to store a solution of CrCl3 in an aluminum container. CrCl3 is a corrosive substance and can react with aluminum to produce hydrogen gas and aluminum chloride. This reaction can cause the container to corrode and potentially leak or rupture. It is recommended to use containers made of materials such as glass or plastic that are compatible with CrCl3 for safe storage.

To determine whether a solution of CrCl3 can be stored in an aluminum container, we need to consider the compatibility of the two substances and whether any chemical reactions would occur.

Chromium(III) chloride (CrCl3) is a compound that contains chromium in its +3 oxidation state. Aluminum, on the other hand, is a reactive metal that can form a protective oxide layer on its surface, acting as a barrier against further reactions.

While it is generally safe to store most solutions in aluminum containers, chromium(III) chloride is an exception. It can react with aluminum to form aluminum chloride (AlCl3) and chromium metal. This reaction is exothermic and can lead to the release of heat and potentially even an explosion in certain conditions.

Therefore, it is not recommended to store a solution of CrCl3 in an aluminum container. It is safer to use containers made of materials like glass, polyethylene, or polypropylene which are compatible with chromium(III) chloride and do not react with it.
