How to identify aluminum ions
University analytical chemistry identification method: 3H3H2O+Al3+= Al (OH) 3+3H4+Al (OH) 3+3C14H6O2 (OH) 2 (alizarin)-Al (C14H7O4) 3Red +3H20 Middle School will not identify Al qualitatively. Hydroxide is also soluble in strong alkali. If you are in middle school, it is enough to know that Al(OH)3 is soluble in strong alkali.
