I dont unerstand it! :? :? :?
And if Aluminium is placed in an acid, will it react? I m guessing no, because of the protective oxide coating on the surface? If so, how come metals such as magnesium react with acid? Why dont their oxides coating protect them?
And finally, is Calcium hydroxide soluble?. Can someone please tell me which metal oxides and hyroxides are solubale, cause i'm really confused with solubility
Thanks a million, and good luck!
