The only materials i can use is iodine, water, HCl, magnet, and pH paper. How do you identify aluminum with that?To start with, are you refering to aluminum as metal, an aluminum compound, or a solution with aluminum present as ions? If it is metaallic aluminum, it won\'t stick to a magnet, and it will react with HCl, however this isn\'t sufficient to definately say it is aluminum, it would be better to get a density, melting point, etc.Other related question
