Due to amphoteric nature of Aluminium, there is a reaction between Al and alkalis. Hence alkalis can't be stored in aluminium containers.
Also, sulphuric acid oxidises aluminium to aluminium sulphate and therefore cannot be kept in it.
And, on heating aluminium with sulphur aluminium sulphide is obtained!
